ABSTRACT:
A phase detector for indicating the magnitude of a phase difference between two electrical signals applied to it, is provided with means for introducing a deliberate phase shift into one of the signals so that the measured phase difference never closely approaches 0.degree. or a multiple of 360.degree.. The detector is capable of providing a smooth output signal over a very wide range of phase difference which can exceed many multiples of 360.degree.. Furthermore, the phase comparator is never required to perform measurements in those regions of least accuracy close to zero phase difference.
