OUESTION 1 Anna is designing an audio amplifier for her headphones. She wants to calculate the real DC gain of the amplifier before putting music through it to make sure it won't destroy her headphones. She has setup a test circuit of the non-inverting amplifier shown below. She has used a cheap poor quality op-amp where the input resistance is 1 kQ, the output resistance is 4 Q and the open loop gain is 100xvin 2Q2 ww 4 2 V...
