What is sampling rate of an audio CD?



- Sampling is defined as ‘the number of samples per unit of time taken from continuous signals for the purpose of making a discrete signal’.

- The unit rate is ‘hert’ for time-domain signals, noted as Sa/s (Samples per Second).

- The time between two samples is known as inverse of sampling frequency.

- The sampling rate for CD should be larger than 40KHz.

- The sampling frequency for audio is higher than the Nyquist rate, as practical filters need to prevent the aliasing to have a finite slope.

- The sampling conversion rate is simplified when the rates are multiples of an integer of each other.
