In a feedback system, the basic amplifier open-loop low frequency gain is 400k and the open loop 3 dB cut-off frequency is 6 Hz. If the required closed loop low cut-off frequency is 200 kHz, calculate the maximum close loop gain of the feedback system and what is your opinion the obtained gain. (b)
