A bandpass filter as shown in Fig. P4–11 has the transfer function
Where the resonant frequency is is a constant, and values for R, L, and C are given in the figure. Assume that a bandpass signal with = 4 kHz and a bandwidth of 200 Hz passes through the filter, where
(a) Using Eq. (4–39), find the bandwidth of the filter.
(b) Plot the carrier delay as a function of about 0.
(c) Plot the group delay as a function of about 0.
(d) Explain why the filter does or does not distort the signal.
