Class Information
Number: 375/242
Name: Pulse or digital communications > Pulse code modulation
Description: Subject matter in which a signal to be transmitted is sampled or compared and then converted into a digital pulse train which represents the amplitude of the sampled signal at the instant of sampling or comparison, and this digital pulse train is transmitted so it may be reconverted into a duplicate of the original signal at a receiver.
