Explanation:
Detailed explanation-1: -It’s measured in “samples per second” and is usually expressed in kiloHertz (kHz), a unit meaning 1, 000 times per second. Audio CDs, for example, have a sample rate of 44.1kHz, which means that the analog signal is sampled 44, 100 times per second.
Detailed explanation-2: -Increasing the sampling rate can improve the quality of the resulting signal, but it also increases the computational requirements. This is why many digital audio applications use a lower sampling rate than the standard 44.1 kHz.
