Question

In the circuit below C1 = C2 = 1 mF and R1 = R3 = 1 kOhm. If the transfer function H(s) = Vout(s)/Vs(s) = H1(s)H2(s) = -1/s + 4 times -1/s + 2, We assume that H1(s) = -1/s + 4 corresponds to the first stage (first op amp circuit). Find the necessary values for R2 and R4 (in Ohm) respectively. Then determine the impulse and step responses. The impulse response is the response due to an impulse function input Assuming zero initial conditions; the step response is the response to a step function input assumine zero initial conditions. Compute H1(s) = V1(s)Vin(s), H2(s) = V (s)V1(s), and H(s) = H1(s)H2(s) = Vout(s)/Vin(s) assuming that c1 = 1 mF, R1 = 1 kOhm, c2 = 1 mF, R2 = 10 kOhm, R3 = 2 k Ohm, c3 = 0.5 mF, c4 = 0.05 mF, and R4 = 200 kOhm. The point here it to solve two simple problems before solving the more complex problem of finding the transfer function of the cascaded network. After finding the transfer function compute the impulse and step responses.
