I have two signals A and B. Both are 50 Hz signals. A is of the form V1sinwt and B is V2sine(wt+phi). Now I have used multiplier and the output is DC=(V1*V2/2)*cos(phi). I am facing issue that if V1 changes then the DC output also changes giving in correct phase readings. How can I make the DC output insensitive to the magnitude of reference A?
