Question

Why a sampling rate of 16,000 hz is typically used?

Answer 1

In signal processing, sampling is the reduction of a continuous-time signal to a discrete-time signal. A common example is the conversion of a sound wave (a continuous signal) to a sequence of samples (a discrete-time signal).

A sample is a value or set of values at a point in time and/or space.

A sampler is a subsystem or operation that extracts samples from a continuous signal.

A theoretical ideal sampler produces samples equivalent to the instantaneous value of the continuous signal at the desired points.

Answer 2

Normally used sampling rates are between 8 kHz (telephone quality) and 48 kHz (DAT tapes). Sampling rates are usually quoted in Hz or kHz (kilohertz).
