Comprehensive Review of Pulse Code Modulation (PCM) and Communication Systems Laboratory Experiments

This document provides a detailed overview of laboratory experiments focused on Pulse Code Modulation (PCM) and related telecommunications systems. It covers fundamental concepts such as sampling, natural sampling, sample-and-hold techniques, quantization, and modulation schemes including Differential PCM and Delta Modulation. Furthermore, it explores transmitter and receiver filter designs, Additive White Gaussian Noise (AWGN) analysis, and various modulation techniques like M-PSK, QPSK, and M-QAM. The review also includes calculations for Bit Error Rate (BER) in Gray-coded 8-PSK and QPSK systems.
