For a transistor amplifier, the voltage gain

Options

A. remain 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 if the above

Answer

C

Explanation

For a transistor amplifier, the frequency-response curve indicates that the voltage gain is low at high and low frequencies and constant and high in the middle frequency range.
