Unit 10 Assignment 2 Signal theory Digital signalling methods Digital signal processing (DSP) are procedures which are used to enhance accuracy of data which is transmitted to improve accuracy of data which is transmitted. One example of this would-be radios which use radio waves. Bits and Bytes bits are tiniest units of data in computers which is known as binary digits. Each bit has a binary value of either 0 or 1, while as multiple bits are known as bytes. Bytes is known for multiple bits which

current are the analog of the voice pattern. The digital signal is different form an analog because a digital signal is not as complex, a digital transmission uses pulses representing one bits and zero bits. Presently we use a combination of both analog and digital networks. In different areas of the network it is necessary to use analog and digital. A codec, which is a combination, is the words “coder” and “decoder” converts the analog signal to digital. There are various types of codecs for various

controlled and manipulated, the variable of interest in the process (e.g. Temperature, Pressure or Flow) often called the Process Variable (PV) needs to be measured by a sensor which converts the measurement into a suitable signal format (4 – 20mA or digital) and then transmit it to a controller which makes the control decision and finally acts on a final control element in the control loop. What does this signal transmission is referred to as a transmitter. The schematic below illustrates the interactions

ANALOG AND DIGITAL SIGNAL 1.1 Analog signal An analog or analogue signal is any continuous signal for which the time varying feature (variable) of the signal is a representation of some other time varying quantity, i.e., analog to another time varying signal. For example, in an analog audio signal, the instantaneous voltage of the signal varies continuously with the pressure of the sound waves. It differs from a digital signal, in which a continuous quantity is represented

we first show the pervasiveness of the mini shakeout phenomena. We then examine why some industries are more likely to experience a mini shakeout. Finally, using detailed quantitative and qualitative data on the emergence of handheld computers and digital cameras, we investigate why some firms abandon

A background subtraction technique is presented in this paper that learns the variation of each pixel throughout the video in terms of differences of averages. And also the pixels colors of current frame with previous frame are learnt with average differences. Background subtraction differentiating foreground objects from the stationary parts of the scene is one of the modules of annotation. Valuable low level cue information is obtained by the module for performing high-level tasks of motion analysis
