Why do we need to compress the signal?

The object of signal compression is to facilitate transmission, reception, processing, and the use of great amounts of data while conserving valuable storage space and transmission resources.

Why do we want to discretize a signal?

Sampling discrete-time signals, i.e., using only every Nth sample of a sequence of samples, is useful for efficiently processing, transmitting, or storing information, if we can be sure that the sampling rate can be reduced without significant loss of information.

What is a compressed signal?

Signal compression is the use of various techniques to increase the quality or quantity of signal parameters transmitted through a given telecommunications channel. Types of signal compression include: Bandwidth compression.

Can digital signals be compressed?

Digital signal processing is more secure because digital information can be easily encrypted and compressed.
