PCM-Zeitmultiplexnachrichtensystem

摘要

A multiplex transmission device includes pulse timing generating apparatus for generating channel sampling pulses and group sampling pulses whereby the time slots of the lowest frequency group at the input are successively divided to provide higher ordered groups of information at higher frequencies. A repeater station for combining and dropping groups or portions of groups of PCM signals in a multi-channel time division multiplex transmission system provides circuitry for generating timing control signals from groups of the multiplex signals to delay and/or inhibit select portions of selected information groups to either combine or drop selected information therein from the transmitted signal groups. The control circuitry utilizes either feed forward or feedback techniques.
