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.
The White Book refers to a standard of compact disc that stores pictures and video. CD-i Bridge [18] - a bridge format between CD-ROM XA and the Green Book CD-i, which is the base format for Video CDs, Super Video CDs and Photo CDs. VCD (Video) – a standard jointly developed and published by JVC, Matsushita, Philips and Sony. [19]
The company's first announced product was the PCM-12, a 12-bit minicomputer based on the Intersil IM6100 microprocessor, allowing it to be mostly software compatible with Digital Equipment Corporation's PDP-8/E. [4] The PCM-12 supported up to 32 kilowords of memory 12 bits wide, [5] and its 80-line bus accommodated 15
G.711 is a narrowband audio codec originally designed for use in telephony that provides toll-quality audio at 64 kbit/s. It is an ITU-T standard (Recommendation) for audio encoding, titled Pulse code modulation (PCM) of voice frequencies released for use in 1972.
A PCM signal is a sequence of digital audio samples containing the data providing the necessary information to reconstruct the original analog signal.Each sample represents the amplitude of the signal at a specific point in time, and the samples are uniformly spaced in time.

The Meridian Lossless Packing logo The Advanced Resolution logo. Meridian Lossless Packing, also known as Packed PCM (PPCM), [citation needed] is a lossless compression technique for PCM audio data developed by Meridian Audio, Ltd. MLP is the standard lossless compression method for DVD-Audio content [1] (often advertised with the Advanced Resolution logo) and typically provides about 1.5:1 ...
Differential pulse-code modulation (DPCM) is a signal encoder that uses the baseline of pulse-code modulation (PCM) but adds some functionalities based on the prediction of the samples of the signal. The input can be an analog signal or a digital signal .
