Circuit's Functions The total wave synchronous detection circuit which is widely used inthe low frequency range and its output pulse wave does not contain fundamental wave.Thus its requirements on low-pass filter cutoff performance can be relaxed.Half wave output circuit switch rectifier high frequency parts of Switch Circuit's Half Wave Synchronous Detection Circui can be showed as the formula:e1=1/π+1/2sinwt-2/3coswt+2/15cos4wt……In the formula,the first one was the DC component and the second is the base wave, the amplitude is 1/2. This circuit is total wave rectifier system and its formula is e0=2/π-4/3sin2wt-4/15sin4wt…… The DC component is 2π and it's bigger than the former because there is no fundamental wave.Thus the filter filers the higher harmonic for over 2 times.
