(a) The open-loop low-frequency voltage gain of an amplifier is A_v = 5 × 10⁴ and the open-loop 3 dB frequency is f_H = 10 Hz. If the closed-loop low-frequency gain is A_{v f} = 25, what is the closed-loop bandwidth?

(b) The minimum closed-loop bandwidth of a feedback amplifier is to be 20 kHz. The open-loop low-frequency voltage gain is A_v = 10⁵ and the open-loop 3 dB frequency is f_H = 8 Hz. What is the maximum closed-loop voltage gain?
