In some applications, band-pass filters are used to pass only those signals having a specified frequency o0. The cutoff frequencies of the band-pass filter are specified to satisfy ffiffiffiffiffiffiffiffiffiffiffi oaob p o0. The transfer function of the band-pass filter is given by HB s k o0 Q s s2 o0 Q s o0 2 0 B@ 1 CA m The order of this band-pass transfer function is n 2m. The pass-band gain is k. Transfer functions of the type are readily implemented as the cascade connection of identical secondorder filter stages. Q is the quality factor of the second-order filter stage. The frequency o0 is called the center frequency of the band-pass filter. Obtain the transfer function of a fourthorder band-pass filter having a center frequency equal to 250 rad/s and a pass-band gain equal to 4. Use Q 1.
