What should be the sampling frequency?

The sampling frequency or sampling rate, fs, is the average number of samples obtained in one second, thus fs = 1/T. Its unit is sample per second or hertz e.g. 48 kHz is 48,000 samples per second.

What is the maximum sampling frequency?

Theoretically the maximum frequency that can be represented is half the sample rate (known as the Nyquist frequency). In practice, the limit is a little lower, so the practical upper frequency limit for a sample rate of 44,100 Hz, is a little over 20,000 Hz, but less than 22,050 Hz.

What is sampling rate in digital signal processing?

Definition: Sampling rate or sampling frequency defines the number of samples per second (or per other unit) taken from a continuous signal to make a discrete or digital signal.

How does sampling frequency affect quality of digital signal?

If the sampling frequency is too low, aliasing distortion can result. Aliasing is a major concern when using analog-to-digital conversion. Improper sampling of the analog signal will cause high-frequency components of the signal to be aliased with genuine lower-frequency components.
