Two amplifiers are operated at the same center frequency f0). Which of the following statements is true?
A) The amplifier with the higher roll-off rate has the wider bandwidth.
B) The amplifier with the lower roll-off rate has the wider bandwidth.
C) The bandwidth of each circuit is not related of its roll-off rate.
D) The bandwidth of each circuit equals the product of its voltage gain and roll -off rate.

Question

Quizplus · Accepted Answer

The bandwidth of an amplifier is inversely related to its roll-off rate. A higher roll-off rate means the amplifier's gain decreases more quickly outside the passband, leading to a narrower bandwidth. Conversely, a lower roll-off rate indicates a slower decrease in gain, resulting in a wider bandwidth.
