12–7 Find the transfer function TVðsÞ =V2ðsÞ=V1ðsÞ of the circuit in Figure P12–7.

(a) Find the dc gain, infinite frequency gain, and cutoff frequency.

Identify the type of gain response.

(b) Sketch the straight-line approximation of the gain response.

(c) Calculate the gain at ω=0:1 ωC, ωC, and 10 ωC.

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

(e) What element values would you change to increase the passband gain by a factor of five without changing the cutoff frequency?
