Pulse Code Modulation(PCM): Pulse Code Modulation(PCM) is different from the other forms of pulse modulation studied so far, PCM also uses sampling techniques, but it differs from the others in…
Pulse Width Modulation(PWM): Pulse width modulation of PTM is also often called Pulse Duration Modulation (PDM). In this system, shown in Fig. 18.8, we have a fixed amplitude and starting…
Types of Encoders in Digital Electronics: By the use of a digital code, it is possible to identify the position of a movable test piece in terms of a binary…
Signal Conditioning of Inputs: Since all the data that have to be acquired, do not generally originate from identical sources, signal conditioning becomes necessary in some cases. A simple attenuator,…
Electric Drive Motor: Motion control is required in large number of industrial and domestic applications like transportation systems, rolling mills, paper machines, textile mills, machine tools, fans, pumps, robots, washing…
Resonant Coaxial Wavemeter: A Resonant Coaxial Wavemeter line such as illustrated in Fig. 16.1 and operating as a resonant system can be used to measure frequencies in the range of…
Typical Digital Filtering Operations: Digital filters in fact can be applied in many different parts of a signal and image processing transmission system. Two typical examples of systems in which…
Frequency Domain Representation: Frequency Domain Representation - A very important representation of discrete time systems can be obtained in terms of sinusoidal or complex-exponential signals. This is possible because the…
