Quizplus · Accepted Answer

Pulse Code Modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form of digital audio in computers, compact discs, digital telephony, and other digital audio applications. In PCM, the amplitude of the analog signal is sampled at regular intervals and each sample is quantized to the nearest value within a range of digital steps.
