A power amplifier with a gain of 100 ∠ 0° has an output of 12 V at 1.5 kHz along with a second harmonic content of 25 percent. Negative feedback is to be provided to reduce the harmonic content of the output to 2-5 percent. What should be the gain of the feedback path and the level of the signal input to the overall system, respectively?
