摘要： A phase measuring and monitoring circuit adapted to measure the phase difference between a reference signal and a monitored signal having a counter switchable to either an add or substract mode, the input to which is a sequence of measured pulses controlled by a filter and zero-crossing detector, the inputs of which are time-shared by the reference signal and the signal to be measured.
