Which of the following diode is used in adjustable band pass filter electronic circuits?

A)

Zener diode

B)

Tunnel diode

C)

Varactor diode

D)

Schottky diode

Correct Answer : Option (C) : Varactor diode

Explanation : Band pass filter depends upon the value of the resistance and capacitance. In varactor diode, we can obtain capacitance by varying the input voltage. As capacitance becomes adjustable, it can be considered as an adjustable band pass filter.
