This is the synchronous wave detection circuit composed of analog switch. As the circuit is installed with an analog switch, so it can work as the wave detection circuit of the low frequency lock phase amplifier under thousands of HZ of frequency. The analog switch AD7515 shifts the basic input signal quickly, when the switch state is shown in the figure, the non-inverting input terminal of A1 is connected with the earth, the input signal is reversed; when the switch is connected with the lower terminal, the inverting phase input terminal of A1 is connected with the earth, as R1 and R2 distribute the voltage, so that A1 is turned into the amplifier which magnifying time is once.
