1. The problem statement, all variables and given/known data 2. Relevant equations H(s)= Vo / Vi Ideal op amp: V+ = V- Vo = V- 3. The attempt at a solution To simplify the circuit, I noticed that the 200 ohm resistor and 60 microFarad capacitor are in parallel so: Zp = (R/sC) / [(1+sRC)/(sC)] = R / [(1+sRC)] Seeing that the Zp is in series with the 5 ohm resistor, I went ahead and used the voltage divider in search of Vo / Vin for the transfer function: V- = 5 / [ 5 + (200/1+s(200)(60^-6)) ] * Vo This is the part where I stopped since I'm not quite certain on how I can relate this to Vin. Can somebody lead me to the right track? Thank you!
