A study is carried out on the design of Pulse Code modulation (PCM) as one of the digital source coding techniques of Digital Communication. The main objective of the e ective Digital Communication process is to reduce the bandwidth. The Source Coding Technique is a type of Analog to Digital Conversion. In this paper, I have focussed on the processes like sampling, quantization and encoding. The types of sampling, quantization and encoding techniques are discussed in detail. For e ciently representing the information in the binary format after encoding from the analog source and also reducing the size of data by reducing the no of bits, Pulse Code Modulation is used. The main objective is to reduce the noise by transmitting the digitized signal. Pulse Code Modulation is designed using MATLAB Simulink.
