=> Vo= { Vx×Vy× [cosθ-(cosθ×cos2ωt)+(sinθ×sin2ωt)]}/(2×Vref). 4. How to remove the dc term produced along with the output in frequency doubler?
A. Use a capacitor between load and output terminal
B. Use a resistor between load and output terminal
C. Use a Inductor between load and output terminal
D. Use a potentiometer between load and output terminal

Explanation: The output of the frequency doubler contains a dc term and wave of double frequency. The dc term can be easily removed by using a 1µF coupling capacitor between load and output terminal of the doubler circuit. 5. Find the voltage range at which the multiplier can be used as a squarer circuit?
