12–4 Find the transfer function TVðsÞ =V2ðsÞ=V1ðsÞ 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 ω=0:1ωC, ωC, and 10ωC.

(d) Use Multisim 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?
