Hi all, About a month ago I had thought I completed what was the final question of my EE summer assignment... I thought wrong. My professor just posted a final problem, an easier problem involving less work. But I decided to ask for some guidance before continuing. I have also attached an example solution of the problem he's provided. 1. The problem statement, all variables and given/known data (Attachment below - EE P8) In each part of this problem, you will be given an expression for the gain of the above circuit. Assume that you solved the circuit and found the given expression (answer). For each given expression (answer), comment on whether the answer is either correct, plausible, or incorrect. Please state reasoning for the choice you picked. 2. Relevant equations (Attachment below - EE P8) 3. The attempt at a solution My question is, should I begin plugging in 0 for the different resistors as he did in the example solutions? I know it's a completely different circuit than the one that I have, but I thought that might be where I start. Any thoughts and input would be greatly appreciated!
