SpletOf them all, the digital modulation technique used is Pulse Code Modulation P C M. A signal is pulse code modulated to convert its analog information into a binary sequence, i.e., 1s and 0s. The output of a PCM will resemble a binary sequence.

SpletThroughout the past few years, Pulse Code Modulation (PCM), Delta Modulation (DM) and Differential Pulse Code Modulation (DPCM), in digital communication systems, have proven to have unparalleled ...
SpletThe system is highly complex. The system requires more bandwidth. Applications of PPM. It is used in the air traffic control system and telecommunication systems. Remote controlled cars, planes, trains use … SpletThe main key difference between PCM and DPCM are given below: PCM stands for pulse code modulation, DPCM stands for differential pulse code modulation. PCM can be required the highest bandwidth but DPCM required small bandwidth. PCM is comprised of complex notation as to when DPCM has simple notation.
SpletIn the transmitter section of PCM, a low pass anti-aliasing filter is employed, before the sampler, to eliminate the high frequency components, which are unwanted. The signal which is sampled after filtering, is sampled at a rate slightly higher than the Nyquist rate.
SpletPulse Code Modulation is used in long-distance communication. The efficiency of the transmitter in PCM is high. Higher noise immunity is seen. Efficient method. Disadvantages The bandwidth requirement is high. PCM is a complex process, since it involves encoding, decoding and quantisation of the circuit.
