Vo = [5×(sin2π×104t)2 ]/10 = 2.5×[1/2-(1/2cos2π ×2×104t)] = 1.25-(1.25×cos4π×104t). 6. 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
Answer:A
Vo = [5×(sin2π×104t)2 ]/10 = 2.5×[1/2-(1/2cos2π ×2×104t)] = 1.25-(1.25×cos4π×104t). 6. 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
Explanation: Vo= [Vmx×Vmy /(2×Vref)] ×cosθ
