What Is Sampling?

- Jul 02, 2018-

Sampling is the process of taking out the instantaneous value of the original analog signal in a digital pulse code to form a series of pulse signals with different amplitudes. In order to ensure the signal recovery, the interval time of the instantaneous value may be determined by the sampling theorem. The sampling frequency must be greater than twice the maximum frequency of the analog sound signal; otherwise the high-end frequency reduction effect of the sound signal will be distorted.
