Application Of Pulse Code Modulation. Thereby generating a discrete signal. The digital code is stored in the memory and which is later re called for the playback.

Of them all the digital modulation technique used is pulse code modulation p c m. The compact disc cd is a recent application of pcm. The signal is continuously sampled.
It is used in telephony.
The code is binary number when sufficient quantizing levels are used the signal will resemble the same as is from an analog system. The output of a pcm will resemble a binary sequence. In a pcm stream the amplitude of the analog signal is sampled regularly at uniform intervals and each sample is quantized to the nearest value within a range of digital steps. It is used to compress data and hence it is used for storage.
