Abstract

A selective receiver of repetitive binary signals is used with time multiplexing transmission systems and when repetitive signals are sent to fully utilise the capacity of the channel. The receiver compares the repetitive messages received and decides on the validity of the message. An input shift register which the successive bits of the repetitive message, a counter driven by a clock and a second counter connected to the first counter and counting the number of times the message has been repeated. It also has a memory which is loaded from the input register and a memory loading control circuit which generates a signal each time there is identical messages in the input register.
