Webe o (t) = AB/2 sin(ϴ i-ϴ o). Where AB=2 & (ϴ i-ϴ o) is the phase difference. If there is a non-zero phase difference, then the loop filter will produce a voltage signal proportional to the phase difference. Due to this voltage signal, the output of VCO is maintained.. How It Works. As long as there is a phase difference it will keep maintaining its frequency until it is locked.
