Question:

For a transistor amplifier, the voltage gain

(a) remains constant for all frequencies.

(b) is high at high and low frequencies and constant in the middle frequency range.

(c) is low at high and low frequencies and constant at mid frequencies.

(d) None of the above.

Answer:

The voltage gain of a transistor amplifier is constant at mid frequency range only. It is low at high and low frequencies.

Hence, the correct statement is (c).
