The bandwidth of an amplifier is
A) the range of frequencies over which gain remains relatively constant.
B) the range of frequencies between its lower and upper 3 dB frequencies.
C) the difference between fc2 -and fc1.
D) All of the above.

Question

Quizplus · Accepted Answer

The bandwidth of an amplifier is defined as the range of frequencies over which the amplifier maintains a consistent gain, typically measured between the lower and upper 3 dB points (fc1 and fc2), where the output power drops to half its peak value. Thus, it encompasses all the given descriptions.
