Web Reference: Pulse-code modulation (PCM) is a method used to digitally represent analog signals. It is the standard form of digital audio in computers, compact discs, digital telephony and other digital audio applications. Di erential PCM PCM uses a lot of bits per second. This is mostly because audio has a large dynamic range, and is weighted towards lower frequencies. The result is that samples are highly correlated, and the previous sample is a good prediction of the next. A signal is pulse code modulated to convert its analog information into a binary sequence, i.e., 1s and 0s. The output of a PCM will resemble a binary sequence. The following figure shows an example of PCM output with respect to instantaneous values of a given sine wave.
