ABSTRACT:
The phase detection circuit includes a first phase detector for receiving an input signal and a first reference signal, a second phase detector for receiving the input signal and a second reference signal having a different phase from that of the first reference signal and a level discriminator for receiving the phase detection output of the first phase detector. The detection operation of the second phase detector can be inhibited directly by means of the discrimination output of this level discriminator. Accordingly, the phase detection output can be obtained from this phase detection circuit only when the phase difference between the input signal and the first reference signal falls within a predetermined range. The phase detection circuit having such a limiting function is suitable for application to an automatic tint control circuit of a color television receiver.
