The basic amplifier in a feedback configuration has a low-frequency gain of \(A=5000\) and two pole frequencies at \(f_{3-\mathrm{dB} 1}=10 \mathrm{~Hz}\) and \(f_{3-\mathrm{dB} 2}=2 \mathrm{kHz}\). The low-frequency closed-loop gain is \(A_{f}=100\). Determine the two \(3 \mathrm{~dB}\) frequencies of the closed-loop system.
