Digital Modulation Techniques: An information bearing signal can be transmitted from one point to another point over a communication channel by using either an analog technique or digital modulation techniques.…
Characteristics of Data Transmission Circuits: Bandwidth Requirements - Characteristics of Data Transmission Circuits is the most instances consists of pulse-type energy. The data stream is similar to a square-wave signal…
Filters in Electronic Instrumentation Articles: What is a Filter Circuit?: A network designed to attenuate certain frequencies but pass others without attenuation is called a filter. A filter circuit thus…
Pulse Time Modulation(PTM): In Pulse Time Modulation the signal is sampled in the same way as in PAM, but the pulses indicating instantaneous sample amplitudes have a constant amplitude themselves.…
