Abstract
Successively larger fractions of a first composite signal are compared with an entire second composite signal to obtain control signals. The composite signals comprise similar direct components with push-pull a-c signals superimposed thereon. One of these control signals may be used to standardize the average amplitude of the push-pull signals by causing them to be attenuated when they exceed a given amplitude, and at least one other, for controlling the synchronous regeneration of the a-c signals. The invention is useful for PCM repeaters in telephone cables.
