4) Please answer in legible and orderly handwriting. If it is not legible, I will not give a positive rating.
Need assistance with solving equation (3.69) to (3.70). I'm not understanding why output voltage is outside of parenthesis in equation 3.70 and the # 1 is on inside of parenthesis?
This is not part of a graded assignment, I'm reading through the chapters and solving examples.
