ABSTRACT:
A digital transmission system for transmitting quantized values of the exmal points of an analog wave. A PCM encoder quantizes the extremal points which are detected by an extremal detector. The PCM digital elements are transmitted to a first-in-first-out buffer under the control of a buffer control logic which is fed information concerning the rate of occurrence of the extremal points. The number of PCM digital elements transmitted will vary in number in accordance with a rule which is a function of the rate of occurrence of the extremal points. Generally, the number of elements per extremal sample decreases when the rate of occurrence of extremal samples increases and vice versa.
