Inputs A, B to be compared are squared, and fed to respective divider chains N A , M A , N B , M B  to produce outputs which are applied via one-in- (L+ 1) decoders DECOD A, DECOD B to set and reset inputs of bi-stables FL 0  ... FL L . When the two signals have the same frequency, the number of bi-stables having a " 0 " (or having a " 1 ") output is indicative of the phase difference, and these outputs are summed via weighting resistors to produce an analogue output which is filtered and fed to a limiter CGCM to produce a constant level output for phase differences above the predetermined value. The outputs from the divider chains are also applied to a comparator COMP and, when the two signals have different frequencies, an output is supplied on line 90 to a cycle suppressor CSC which suppresses pulses in the higher frequency pulse train so that the comparator output remains constant.
