Question # 5 (a) Find an expression, in terms of R, L, and C, for the resonant frequency, Wo, of the circuit shown in Fig. 5(a). Use this expression to find the resonant frequency when R = 501, L = 40mH, and C = 1uF. = с ele R w Fig. 5(a) (b) Design an active lowpass filter shown in Fig. 5(b) that provides a dc gain of 0.25 and has a cutoff or corner frequency of 500 Hz. Assume Rf 20kN. Specifically, find the values of Rị and Cf. Also, find the magnitude and phase of the transfer function of the filter at the cutoff frequency. R C HE R + + V Fig. 5(b)
