Codecs for P.C.M. processing
Abstract
The need for PCM systems in telecommunications has prompted the development of LSI codecs. This paper describes the design, principal characteristics, and fields of application of codecs. Attention is given to the principle of operation, the A/D conversion process, chip features, basic waveforms, operating frequency limits, synchronization of coder and decoder, gain tracking, and signal/distortion figures
