<p>A reference pulse signal is applied to both a detector multiplier and a gate circuit by utilizing the same transmission path, i.e., same circuit. More specifically, the reference pulse signal is supplied to the detector multiplier and gate circuit through a transistor and a resistor. Therefore, the reference pulse signal received at the base of the transistor constituting the detector multiplier is substantially identical in level and pulse width to the reference signal received a-t the base of the transistor constituting the gate circuit. Owing to the use of the same transmission path described above, the timing of pulse detection coincides very accurately with the timing of gate control. Therefore, a signal can be detected accurately and the efficiency of phase detection is improved.</p> |
