# Pulse-code modulation (PCM) is a digital representation of 
# an analog signal where the magnitude of the signal is sampled 
# regularly at uniform intervals, then quantized to a series of 
# symbols in a digital (usually binary) code. 
# PCM has been used in digital telephone systems and is also the standard
# form for digital audio in computers and the compact disc red book format. 
# It is also standard in digital video, for example, using ITU-R BT.601. 
# However, straight PCM is not typically used for video in consumer 
# applications such as DVD or DVR because it requires too high a bit rate 
# (PCM audio is supported by the DVD standard but rarely used). 
# Instead, compressed variants of PCM are normally employed. 
# However, many Blu-ray Disc movies use uncompressed PCM for audio. 
# Very frequently, PCM encoding facilitates digital transmission from 
# one point to another (within a given system, or geographically) in serial form.
