...EE212 | ANALOG ELECTRONICS I LAB 5– DC BIASING AND OPERATION OF A BJT AMPLIFIER 2016 Particle members Rajinesh Lal S11096112 Nawazish Ali S11120551 Semester 8-11am Date: 12/04/2016 AIM * measure and calculate the DC voltage and current at the base, collector, and emitter of a common-emitter amplifier with voltage divider bias, * measure the input and output voltage and current of a common-emitter amplifier, * measure the phase-shift between the input and output voltages, * calculate the voltage, current, and power gains of a common-emitter amplifier, and * investigate the use of a BJT as a switch. THEORY The biasing of a transistor is purely a dc operation. The purpose of biasing is to establish a Q-point about which variations in current and voltage can occur in response to an ac input signal. In applications where small signal voltages must be amplified— such as from an antenna or a microphone—variations about the Q-point are relatively small. Amplifiers designed to handle these small ac signals are often referred to as small-signal amplifiers. Three amplifier configurations are the common-emitter, the common-base, and the common-collector. The common-emitter (CE) configuration has the emitter as the common terminal, or ground, to an ac signal. CE amplifiers exhibit high voltage gain and high current gain. * common-emitter amplifier with voltage-divider bias and coupling capacitors C1 and C3 on the input and output and a bypass...

...identify and manage polarity within an organization is critical to its success. Within an organization, group, or team there are two categories of polarities that can be identified. Affective polarity refers to the interpersonal struggle based on the informal characteristics among the group or team members and substantive polarity refers to the intellectual struggle based on task-oriented opposition. (van Engelen, Kiewiet, & Terlouw, 2001, p. 50) Polarities are normally viewed negatively because they hamper the progress of work within a team, group, and organization and many believe they should be avoided or immediately resolved. (Kratzer, Leenders, van Engelen, 2006, p. 97) However, some believe that it is only through conflict and disagreement can a team, group, or organization gain ground breaking innovation and progress. (van Engelen, Kiewiet, & Terlouw, 2001, p. 48) To capitalize on the progress that can be gained from a conflict, it must be managed effectively. There are some polarities that are continuous within a team, group, and organization and must be properly managed by the leaders. A study by Thomas and Schmidt found that managers “have to spend over 20 percent of their time in handling conflict.” (Kratzer, Leenders, van Engelen, 2006, p. 97) There are six major polarities that leaders must manage effectively. These polarities include: 1. Big picture versus attention to details – Leaders must be able to keep the future “completion...

...The terms team and group can sometimes mean the same thing according to individuals; however, there is a difference between the two especially in an organizational setting. In this paper, the topic for discussion will analyze the differences between a group versus a team, examine workplace diversity, and how it relates to team dynamics. Leadership in organizations generally stress the important factors of teams and team building, not referring to a group for example. A team’s weaknesses and strengths depend on the interconnectivity from the individuals in the team as opposed to a group where their strengths generally come from a leader and their willingness to carry out commands. Organizations believe that is can be much simpler to form a group versus a team. Individuals can be grouped together according to experience, gender, age, etc. The interpersonal dynamic of a group can differ between compatibility to intolerance which in turn can be difficult for a single leader. A team can be difficult to form because they may be formed according to skill level and the compatibility of their skills as opposed to a commonality. Each individual has a specific importance, function, and purpose within the team so their success is driven by the individual’s interpersonal dynamic with one another. When working in a team-based environment, it is difficult when conflict arises because it could potentially affect the performance of the team as a whole. In order for a group to find...

...Are You A Good Communicator? Communication is the process of sharing one’s information to another person or a group of people whether it is one’s thoughts or his or her feelings through spoken words, written words, or body language. Effective communication requires that the transmitted information is received and understood by the receiver in the way it was intended. Interpersonal relationships are important particularly in the health care industry for teamwork and forming positive working relationships between the health care team and their patients. Trust in health care is an important interpersonal skill and the cornerstone of effective doctor-patient relationships. “The need for interpersonal trust relates to the vulnerability associated with being ill. Without trust patients may well not access services at all, let alone disclose all medically relevant information” (Rowe & Calnan, 2006, p4). Trust is also an important interpersonal element in effective healthcare team development. A supportive climate encourages open, honest, and constructive interactions among informal conversations and formal conversations. While a defensive climate leads to competitive or even destructive conflict. According to Dr. Jack Gibb, who was a distinguished psychologist and a consultant for various organizations for five decades, there are six dimensions of behavior. Each dimension has an opposite or polar end. One side of the dimension creates a defensive climate, while the opposite...

To know basic approach to Job Evaluation. 2. To importance of Job Evaluation and its effectiveness. 3. To know the important methods of Job Evaluation. Now friends we will discuss about how jobs used to be evaluated in an organization; if somebody having any idea about it please start explaining it; this can be explained in the following way. Job evaluation is the process of analyzing and assessing the various jobs systematically to ascertain their relative worth in an organization. Job is evaluated on the basis of their content and is placed in the order of their importance. It should be noted that in a job evaluation programme, the jobs are ranked and not the jobholders. Jobholders are rated through performance appraisal. “Job evaluation is a process of finding out the relative worth of a job as compared to other jobs” Now, who is going to explain the objectives of job evaluation? The following objectives are derived from the analysis of the above-mentioned definitions: 1) To gather data and information relating to job description, job specification and employee specifications for various jobs in an organization. 2) To compare the duties, responsibilities and demands of a job with that of other jobs. 3) To determine the hierarchy and place of various jobs in an organization. 4) To determine the ranks or grades...

...organizes them into groupings based on their natural relationships (Viewgraph 1). The Affinity process is often used to group ideas generated by Brainstorming. Why should teams use the Affinity process? The Affinity process is a good way to get people to work on a creative level to address difficult issues. It may be used in situations that are unknown or unexplored by a team, or in circumstances that seem confusing or disorganized, such as when people with diverse experiences form a new team, or when members have incomplete knowledge of the area of analysis. When should we use the Affinity process? The Affinity process is formalized in an Affinity Diagram and is useful when you want to (Viewgraph 2) Sift through large volumes of data. For example, a process owner who is identifying customers and their needs might compile a very large list of unsorted data. In such a case, creating an Affinity Diagram might be helpful for organizing the data into groups. Encourage new patterns of thinking. An Affinity exercise is an excellent way to get a group of people to react on a "gut level" rather than mulling things over intellectually. Since Brainstorming is the first step in making an Affinity Diagram, the team considers all ideas from all members without criticism. This stimulus is often enough to break through traditional or entrenched thinking, enabling the team to develop a creative list of ideas. When shouldn't we use the Affinity process? As a rule of thumb, if...

...performances. Specifically dwelling within the thoughts of individualism versus collectivism. Secondly with power distance, uncertainty along with risk avoidance strategies. Finally, the topics of achievement versus nurturing orientation on how the lye on organizational performances. An individualistic society depends upon the values of freedom and independence, while a collectivistic society depends on group harmony and consensus. The values in each society play an intricate role in developing communication styles for a business message targeted at each specific audience (Study). The main advantage of individualism within the business world is the concept of “freedom of speech”. With this process, it allows everyone’s opinions to be heard and also serves as a great check and balance within the team. However with every topic, there is also the down side too. The disadvantage of this is that it enables self-centeredness and if you are one of the weaker ones of the team, it allows you to be pushed around. The entire thought of individualism is for personal gain. Collectivism deals mainly with proper teamwork, minimizing confrontations as much as possible and promoting strong harmony within the team. With this topic it does not allow for true creativity and thoughtful openness to others opinions. But when we compare both of these two side by side, it is completely open to the end state goals of the team to actually decide which one is better for their own purposes. With...

Value & Individual Behavior 4. Personality & Individual Behavior 5. Conclusion 1. Organizational Output by Individual Behavior Some people say organizational output is affected by individual behavior. To examine the statement, let us firstly take a look at individual behavior. 2.2.3 Counterproductive Work Behaviors (CWBs) Counterproductive work behaviors are known as voluntary behaviors that have the potential to directly or indirectly harm the organization1. These behaviors can be intentional or unintentional and result from a wide range of underlying causes and motivations. The variety of acts that are considered CWBs has led to attempts by researchers to create a coherent typology of CWBs. One four-class typology of CWBs divided the CWBs into the following categories: 1. Production deviance - involving poor attendance behaviors like leaving early, intentionally working slow, or taking unnecessarily long breaks; 2...

...Small Team and Group Paper Working as part of a small team or group is inevitable at some point in every person’s career. Whether it is at a food establishment or in an office environment, teams and groups always play a crucial role in the business world. I have worked with several small teams and groups, but the longest I’ve worked in such an environment was as an instructor for the U.S. Army in Arizona. I taught for four years as a contract instructor at the Human Intelligence Collector Course at Fort Huachuca, Arizona. The course was broken down into three detachments numbered One, Two, and Three. Each detachment was broken down into six smaller groups. Each group consisted of approximately six to eight contract instructors, a civilian group leader, and one to three military group leaders or assistant group leaders. Each group consisted of approximately four teaching teams of two to three contract instructors and the rest of the instructors were generally role players or assisted with grading reports. The purpose of each of the teaching teams was to present classes in order to teach the military students the essentials of becoming a Human Intelligence Collector. The breakdown within each detachment generally changed for every class cycle. Each class cycle lasted approximately 18 weeks, sometimes longer with holiday weekends, with about 2 weeks or less in between classes. During the break between classes, the upper management and the military leadership would review input...

...The Forgotten Member Part 1: Group Development Forming Stage: Members in this stage will ask a number of questions as they are still in the process of getting to know one another better. The questions asked can vary. Group members may raise the following questions: "What can I contribute to the group?" "What can the group offer me?" In this stage members are more concerned with getting to know one another a little bit better and learn behavior that's acceptable. Storming Stage - In this stage members tend to be highly emotional and there tends to be a lot of tension in the air. Coalitions and cliques typically form during this stage as members compete to achieve status quo and impose their preferences on one another. This tends to be the most difficult stage to accomplish. Norming Stage - During this stage members are unified. There's now a new sense of harmony following the storming stage and members strive to maintain that harmony. Performing Stage - At this stage we are totally integrated! We now have a well-organized team that functions maturely. We are motivated by team goals and objectives and stable. Additionally, we are satisfied without jobs. At this point we are a High Performance Organization! Adjourning State - Once we have reached the performing stage we are ready to adjourn. At the ‘Adjournment Stage’ the members are able to disband if necessarily, convene quickly, and perform their duties on a tight schedule. Based on the information provided...

...Nonparametric Hypothesis Testing RES/342 Nonparametric Hypothesis Testing During the course of the last three weeks, the team explored the hypothesis testing segment of statistics research. The first part of this assignment was the one sample hypothesis testing. The second was the two or more sample hypothesis testing, and finally in this third week, we will look at nonparametric hypothesis testing. This week’s project is a continuation of the previous projects and entails to build on the identical research question that we will frame a research hypothesis from the same provided data sets (Wage and Wage Earners) using ratio or interval numerical data; however, this week we will use a nonparametric hypothesis test to find our answer. In the next following paragraphs, the team will clearly affirm a hypothesis statement that will provide the base for our survey, perform a five-step hypothesis test on information concerning our choice and apply the concepts of nonparametric testing learned in this course, and describe how the results of our findings answer our research question. Finally, we will conclude this study with a brief summary that will examine the main points, the purpose, and conclusions of this final third week’s study on nonparametric testing.

...effective when creating a new position. There are many different strategies that have been used to determine what type of analysis should be used for what each individual company may need. I came across an article that did a study and review on what KSA’s would be required to do a job analysis that was based on groups, in order to determine what KSA’s are needed for teamwork. The study concentrated on three areas based on groups. The first one was KSA’s instead of personality traits. Second, team KSA’s as opposed to technical KSA’s and last team versus individual analysis. The article stated that focusing on KSA’ s characterize traits such as trust, helpfulness and supportiveness which are all excellent traits to have when working with a team. The study focused more on team instead of technical KSA’s because team was directed more towards social and interpersonal skills that are needed for teamwork. The team versus individual part of the study focused on each individual within the team specifically because each team member is an individual hired separately from the other team members and when they are evaluated that is also on an individual basis. So to focus on the team itself would not be fair to each individual. I read another article that talked about strategic job analysis and hoe the KSA’s are used to measure the effective performance for a job not for now but for that particular jobs existence in the future. The article stated that in order to predict what might happen...
