Pulse code modulation (PCM) is one of the encoding of digital communications, in a communication system will complete the function of digital speech signals. The realization of the PCM mainly includes three steps: sampling, quantization and coding, completed on the discrete time, the amplitude of discrete and quantify the binary representation of signals.
