Question

What is the function of an alpha cutoff frequency?

(a) To simplify the circuit

(b) To provide a non – linear output

(c) To optimize the power

(d) To provide steady current or voltage

I have been asked this question by my college professor while I was bunking the class.

My question is taken from The Alpha Cutoff Frequency in portion High Frequency Transistor of Electronic Devices & Circuits

Answer 1

Right answer is (d) To provide steady current or voltage

To elaborate: The Q – point of a device is the direct current or voltage of a device when no input is applied. The alpha cutoff frequency is a part of the device with provides the steady current or voltage. It is designed by determining the necessary voltage and current levels across each resistor.
