D **14.29 (a) Show that |T| of a second-order bandpass function is geometrically symmetrical around the center frequency ω0. That is, the members of each pair of frequencies ω1 and ω2 for which are related by
(b) Find the transfer function of the second-order bandpass filter that meets specifications of the form in Fig. 14.4 where ωp1 = 8100 rad/s, ωp2 = 10,000 rad/s, and Amax = 3 dB. If ωs1 = 3000 rad/s, find Amin and ωs2.
