Abstract
Disclosed is a full duplex communication system connecting by a two wire link a main station and a local station. Both the main station and the local station has a clock pulse generator. The local clock pulse generator is switchable between a pulse rate which corresponds to that of the main clock and another pulse rate which defers about a fixed value. A comparator compares the phase of the incoming signal with the local clock signal and switches the local clock generator when its output is out of phase with the received signals.
