Abstract
A method and device for phase synchronization for use particularly where a fixed internal clock signal generator is used for both receive and transmit functions. The phase difference between the incoming pulse train and a fixed internal framing clock is detected by a counting circuit which provides an output signal indicating the interval time of the phase difference. A delaying means coupled to the incoming pulse train delays the same in response to the output signal for the time indicated thereby and provide synchronism therebetween.
