Abstract
A technique for pulse code modulation (PCM) encoding according to the 15-segment approximation to the μ-255 nonlinear encoding law is described. The technique makes possible the realization of a one-channel encoder together with the associated sample/hold function as a single NMOS integrated circuit. The requirements imposed on the individual components for satisfactory system performance are investigated, and it is shown that a performance can be achieved which is comparable with that required in toll quality PCM telephone transmission. Experimental results from a partially integrated prototype are presented.Keywords
