An amplifier has values of fc2 = 500 kHz and fc1 = 40 kHz. The center frequency for the circuit is approximately .
A) 141 kHz
B) 230 kHz
C) 270 kHz
D) 460 kHz

Question

Quizplus · Accepted Answer

The center frequency (f0) for a bandpass filter can be found using the formula f0 = sqrt(fc1 * fc2), where fc1 and fc2 are the lower and upper cutoff frequencies, respectively. Plugging in the given values: f0 = sqrt(40,000 * 500,000) ≈ 141,421 Hz or approximately 141 kHz.
