Q.

(a) An audio amplifier with R_i = 10 k, R_o = 0, and ¯A(ω), as shown in Figure (a), is used in the circuit shown in Figure with R_S = 1 k,R_L = 16 , and C = 0.2 µF. Sketch G_V(f ) versus frequency if G_V(f ) is defined by G_V (f ) = |¯V_L|  / |¯V_S|.

(b) Find f_max for this circuit if f_max, the maximum usable frequency, is defined as the frequency at which G_V has dropped 6 dB below its maximum value.
