Abstract
A shift-companded, or n:m, pulse code, representing on a time-amplitude basis the information of a conventional, amplitude companded, pulse code, is converted to a linear, digital, amplitude, pulse code by first converting the shift-companded amplitude information into 2s-complement form with a number of bits sufficient to yield substantially the same resolution of the encoded information as did the shift-companded code form. Thereafter half of the 2s-complement code words are loaded into an accumulator to be averaged. The resulting digital word representing the average is in 2s-complement, linear PCM format and is thus readily useful for data processing or for further conversion to a commercial, companded, transmission code.
