Answer 2

The Nyquist theorem is the principle followed by the engineers in the digitization of the analog signals.

It is also called as sampling theorem.

The sampling frequency or sampling rate is the number of the samples per second.

This theory helps to find out the bandwidth of the higher frequency in an analog signal.
