Abstract

PURPOSE:To secure the decision for gains or losses of the phases between the 1st and 2nd alternating rectangular wave signals through a simple constitution by drawing the output of the 1st wave signal after integration in the form of the phase comparison output via the switch citcuit which is turned on and off in synchronization with the 2nd wave signal. CONSTITUTION:The rear-step integrating circuit comprising resistance 11, operational amplifier 7 and capacitor 12 is provided at the output end of the integrating circuit consisting of operational amplifier 6, resistance 8 and capacitor 10 each. And the output of the integrating circuit is applied to the terminal of the opposite side to the signal input of amplifier 6, and the integrating time of the rear-step intergrating circuit is set sufficiently longer than that of the front-step integrating circuit. Then the 1st alternating rectangular wave signal supplied to the terminal is integrated at the front-step integrating circuit, and the output is drawn out in the form of the phase comparison output via switch circuit 14 which is turned on and off in synchronization with the 2nd alternating rectangular wave signal supplied from terminal 3. In such way, the gains or losses of the phases between the both signals can be decided through a simple constitution even in case one signal to be compared may feature an optional duty factor.
