...------------------------------------------------- ECET-402 Week 2 Lab – Acquiring Temperature & Signal Conditioning This lab actually consists of two separate but related labs. They will be presented in Parts A and B. Objective: The objective of this lab is to use an LM34 temperature sensor to acquire temperature and display it in an 8-bit binary number using LEDs and designing simple signal conditioning circuits using op-amps. Parts Needed: 1. Multisim 8 (or higher) 2. LM34 Temperature Sensor 3. ADC0809 4. 8 LEDs 5. Wires, wire cutter, and wire stripper 6. Adjustable DC Power Supply 7. Function Generator and DMM Part A – Temperature Sensor We will use an LM34 temperature sensor IC to measure temperature in Fahrenheit degrees. We will then convert the analog output voltage of the sensor to an 8-bit digital signal using the Analog to Digital converter ADC0809. Finally we will use 8 LEDs to display an 8-bit binary number representing the temperature. LM34: The LM34 series are precision integrated-circuit temperature sensors. The output voltage is directly proportional to temperature in Fahrenheit degrees. Output voltage increases by 10 mV for every one degree Fahrenheit. For example, an output voltage of 720 mV (0.72 V) indicates a temperature of 72 F. LM34 has a range of -50 to +300° F and can be operated with a voltage supply of 5 to 30 VDC. It draws only 75 µA from its supply...

...Electronics rely heavily on electronic switching and amplification to generate and capture the various signals which allow them to operate. A controllable valve that allows a small signal to control a much larger signal does this, and could be related to a controllable valve used in the control of water flow. This was once done by a device known as vacuum tube but was later brought down to a much lower production scale for a variety of industrial, economical and business related reasons. Bell Laboratories, the research arm of telecommunications company American Telephone and Telegraph’s (AT&T) director Mervin Kelly put together the first team of researchers and scientists placed on the task of research and development of a solid state-semiconductor later called a transistor that would supersede vacuum tubes and provide numerous advantages. The success of this development would prove to change the computing, electronics and telecommunications systems altogether. Up until the invention of the transistor a vacuum tube was used in the control, amplification and generation of electrical signals. Vacuum tubes are tubes usually made from glass and designed in an airtight manner as to keep the flow of “cathode rays” from external disturbance as they pass from each terminal and laid the foundation for numerous technical innovations, such as the light bulb discovered by Thomas Edison (fig. 1). Joseph John Thomson further made a vacuum tube and placed a third terminal to attain a grasp...

...State University of New York at Stony Brook Department of Electrical and Computer Engineering ESE218 Digital Systems Design Lab 9. Counter design. 1. Objectives - Design of the synchronous finite state machine (FSM) with D-flip-flops and multiplexers - Verification of the circuit behavior with a CAD tool 2. Problem description Design the synchronous 4-bit counter which outputs follow the predetermined repeated sequence of states. The sequence of states represents the sequence of decimal digits of your ID number with the following exceptions: (1) digits which appear more than ones have to be deleted; (2) digit 9 has to be added at the end of the sequence if your ID has no 9. For example, for ID number 105123456 the second 1 and 5 are deleted and 9 is added at the end resulting in sequence 10523469. In the binary form the sequence is shown in Figure 1. The initial state is not critical. State 9 should be decoded to generate special signal SYNC shown in denominator in Figure 1. In the prelab: the circuit behavior has to be verified in OrCAD. The maximum clock frequency has to be calculated using timing specs of the flip-flops and multiplexers (logical gates) from datasheet. In the experiment: first, the functionality of the counter has to be tested with a pushbutton that controls the clock and a 7-segment LED display connected to the outputs. Finally, the counter sequence should be demonstrated with the logic analyzer synchronized with SYNC signal, 4inputs of the logic analyzer...

...Major Milestones of the Telecommunications Industry 1837 Samuel Morse invents the telegraph - The information age began with the telegraph, which was invented by Samuel F.B. Morse in 1837. This was the first instrument to transform information into electrical form and transmit it reliably over long distances. The earliest form of electrical communication, the original Morse telegraph of 1837 did not use a key and sounder. Instead it was a device designed to print patterns at a distance. 1858 Transoceanic telegraph cable is laid – The transoceanic telegraph cable is an undersea cable running under the Atlantic Ocean used for telegraph communications. The first communications occurred August 16, 1858, reducing the communication time between North America and Europe from ten days, the time it took to deliver a message by ship, to a matter of minutes. 1876 Alexander Graham Bell invents the telephone - The telegraph was followed by Alexander Graham Bell's invention of the telephone in 1876. The magneto-telephone was one of the first telephones on which both transmission and reception were done with the same instrument. 1885 - Incorporation of the American Telephone and Telegraph company (AT&T). After its incorporation in 1885, the American Telephone and Telegraph company dominated the telecommunications market. 1888 - Heinrich Hertz discovers the electromagnetic wave 1895 - Marconi begins experimenting with wireless telegraph 1901 Guglielmo Marconi invented the radio—the...

...Unit 1 Research 1 PT1420 In the 1970s the programming language that was most popular was Pascal. Pascal was designed in 1968-69 but published in 1970. Niklaus Wirth created the Pascal language to “1) make available a language suitable for teaching programming as a systematic discipline based on fundamental concepts clearly by the language, and 2) to define a language whose implementations could be both reliable and efficient on then-available computers. In 1972 the C programming language was developed by Dennis Ritchie. C was created to work with the system Unix. “Unix gives C such advanced features as dynamic variables, multitasking, interrupt handling, forking, and strong, low-level, input-output. Because of this, C is very commonly used to program operating systems such as Unix, Windows, the MacOS, and Linux.” In the 1980s the popular programming language was C++. C++ was developed at Bell Laboratories. C++ is a general purpose multi-paradigm spanning compiled language that has both high-level and low-level languages’ features. It was started as an enhancement to the C programming language, Bjarne Stroustrup in 1979. In the 1990s Java was the popular programming language. It was created in 1991 developed by James Gosling at Sun Microsystems and release in 1995. In the 2000s Visual Basic (VB) was popular in the programming world. VB was developed from BASIC which was originally developed in 1964 by John Kemeny and Thomas Kurts. VB is a Microsoft programing language and software...
