Definition of "PCM" |
Pulse-Code Modulation (PCM) is the conversion of an analog signal (e.g. audio) into digital, binary (0 or 1), coded pulses, decreasing noise susceptibility. PAM, PFM and PWM are examples of PCM methods. / Phase-change Memory, Pulse code modulation, Powertrain Control Module, Partido Comunista Mexicano (Mexican Communist Party), plug compatible machine , pulse code modulation / Pulse Code Modulation is the conversion of an analog signal into digital, binary (0 or 1), coded pulses, decreasing noise susceptibility. PAM, PFM and PWM are examples of PCM methods. / Plug-Compatible Machine is one that has been designed to be backwards compatible with a prior machine. In particular, a new computer system that is plug-compatible has not only the same connectors and protocol interfaces to peripherals, but also binary code compatibility,it runs the same software as the old system. A plug compatible manufacturer or PCM is a company that makes such products. / In packet mode communication networks, contention is a media access method that is used to share a broadcast medium. In contention, any computer in the network can transmit data at any time. / See pulse-code modulation. |
