Find the transfer function TV(s) V2(s)/V1(s) of the circuit in Figure P124. (a) Find the dc

Find the transfer function TV(s) ¼ V2(s)/V1(s) of the circuit in Figure P12–4.

(a) Find the dc gain, infinite frequency gain, and cutoff frequency. Identify the type of gain response.

(b) Sketch the straight-line approximations of the gain and phase responses.

(c) Calculate the gain at v ¼ 0.5vC, vC, and 2vC.

(d) Use OrCAD to plot the Bode magnitude gain response of the circuit. Validate your answers for part (c).

(e) How many dB down from the passband is the filter at one octave past the cutoff?
