Abstract: PURPOSE:To execute the measurement with high accuracy and with high time resolution in a short time by allowing a timing comparison pulse signal to pass through only while phase difference information signals which are varied in accordance with the phase polarity between input signals to be measured to not coincide. CONSTITUTION:A phase difference detecting circuits S1, S2 output a high level as positive phase shift information, when the timing of a timing comparison pulse PR is delayed comparing with the other timing, and output phase difference information signals OUT+1, OUT+2 of NRZ for outputting a low level as a negative phase shift, respectively, in case of the contrary. As for these signals OUT+1, OUT+2, exclusive OR is taken by an EX-OR gate 4, and also, as for the pulse PR and an output signal EOR of the gate 4, AND is taken by an AND gate 5, and only when the output EOR of the gate 4 is high, the pulse PR is outputted from the gate 5. An output signal AND of the gate 5 is inputted to a clock terminal CK of a counter 6, and the number of pulses is counted.

The specified frequency is a frequency which interferes with a specified unit and about 1,576 MHz inputted to the GPS unit used for car navigation applies to it in this case. The CH 56 (in the case of a Nippon Broadcasting Channel) of television broadcasting exists around it. Then, a desired signal inputted from the input terminal 1 is made to pass without loss by setting the trap frequency of the low-pass filter 3 to about 1,576 MHz. Thus, only secondary higher harmonic from the oscillator 8 at the time of receiving the CH 56 is attenuated.
