Calculate the phase difference between two input signals applied to a multiplier, if the input signals are Vx= 2sinωt and Vy= 4sin(ωt+θ). (Take Vref= 12v).

(a) θ = 1.019

(b) θ = 30.626

(c) θ = 13.87

(d) θ = 45.667

The question was posed to me by my school teacher while I was bunking the class.

I need to ask this question from Multiplier and Divider in portion Operational Amplifier Applications of Linear Integrated Circuits
