In the figure is the synchronous wave detection circuit of full method. In the circuit, A1 and A2 can compose the balance output circuit of forward/backward phase output, even when the R2/R3 ratio is 1. the analog switch AD7512 plays an important role, the figured connector position is the inverting input terminal of the forward output(A1 output is the forward hemi-cycle of the input signal) linking to A3; if the connector is lower, the inverting output (A2 output is the backward hemi-cycle) is conducting. Considering the period of an input signal in the way, A3 output terminal can get a full-wave output.
