C. Double multiplier
D. All of the mentioned
Answer:A
=> lnVx+lnVy = ln(Vx×Vy). 2. Which circuit allows to double the frequency?
A. Frequency doubler B. Square doubler C. Double multiplier D. All of the mentioned
Explanation: The multiplication of two sine wave of same frequency with different amplitude and phase allows in doubling a frequency. 3. Compute the output of frequency doubler. If the inputs Vx = Vsinωt and Vy = Vsin(ωt+θ) are applied to a four quadrant multiplier?
