Everything about Pulse-code modulation
Digital representation of sampled analog signals
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. In a PCM stream, the amplitude of the analog signal is sampled at uniform intervals, and each sample is quantized to the nearest value within a range of digital steps. Claude Shannon, Bernard Oliver, and John Pierce were inducted into the National Inventors Hall of Fame for their PCM patent granted in 1952. Wikipedia →
