Abstract
In a system for processing PCM signals and transmitting such signals over a channel, which system includes an input portion having a circuit for interleaving arriving data words and supplying the interleaved words to the input end of the channel, and an output portion having a circuit for de-interleaving the data words arriving at the output end of the channel so that the data words, after de-interleaving, are present in the sequence existing before interleaving, the interleaving circuit performs two successive interleaving operations on the arriving data words, and the de-interleaving circuit operates in a manner to complement the interleaving circuit.
