If an amplifier has a bandwidth of 47 kHz and a higher cutoff frequency of 104 kHz, the lower cutoff frequency would be
A)151 kHz.
B)104 kHz.
C)47 kHz.
D)57 kHz.

Question

Quizplus · Accepted Answer

The bandwidth of an amplifier is the difference between its higher and lower cutoff frequencies. Given a bandwidth of 47 kHz and a higher cutoff frequency of 104 kHz, the lower cutoff frequency can be found by subtracting the bandwidth from the higher cutoff frequency: 104 kHz - 47 kHz = 57 kHz.
