Which of the following correctly describes how sound is digitized for computer processing?
Sound waves are sampled at regular time intervals.
The amplitude of the sound is measured at each sample.
The amplitude of the sound cannot be measured precisely.
The sound wave is converted to an analog signal.
Explanation
Digitization of sound involves sampling and measuring amplitude at regular intervals. The measurement is an approximate value.
