Question

What is the difference between pulse code modulation and delta modulation? Provide examples.

Answer 1

Explanation:

Pulse code modulation is the technique in which the analog to digital converter, covert the analog waveform into the sampled multi-bit digital code.  Then, the code is basically stored and then recall for the playback.

Pulse code modulation is the method that is used to represent the sample analog signal. Basically, it is in the form of compact discs and various digital audio in the computer system applications.

Delta modulation is the process in which the transmission of data are get reduce by the 1 bit of the data stream. The main feature of delta modulation is that the analog signals are in the series of the segments.  

Example: The pulse code modulation is used in various digital audios application in the computer system.

On the other hand, delta modulation is used in radio and telephone communication.
