Sampling

Sampling: process of taking values (samples) of the analog waveform at regularly spaced time intervals.

Sampling Rate: number of samples taken per second (Hz);
- kHz (professional studio)
- kHz (CD)
- kHz (broadcasting)
Sampling Period: time interval (in seconds) between samples:

$\displaystyle T_s = 1/f_s$ seconds $\displaystyle .$
