Question

a) The figure shows the circuit diagram of an active filter using an ideal operational amplifier. The values of the circuit components are as follows, R1 = 1500 ohms, R2 = 2000 ohms, C1 = 0.1 microfarads, C2 = 0.5 microfarads

The phase shift in degrees through the circuit as frequency approaches infinity is determined as nearest to which of the following answers (A) - (E)

b) The figure shows the circuit diagram of an active filter using an ideal operational amplifier. The values of the circuit components are as follows, R1 = 1500 ohms, R2 = 2000 ohms, C1 = 0.1 microfarads, C2 = 0.5 microfarads. Find the magnitude of the circuit gain vo/vin at zero frequency
