1 ECE 408 HOMEWORK #4 (CH. 13) 1. The normalized analog pole locations of a filter is given by S = -0.3689 S = -0.1845 ± j0.9231 There are three zeros at S = . These poles and zeros are transformed to bandpass poles and zeros. (a) Find the frequency transformed bandpass poles and zeros when ϖ 1 = 1.0691e+004 rad/s and ϖ 2 = 1.6000e+004. (b) Find the digital poles and zeros when the sampling rate is 8000 Hz. 2. The normalized analog pole locations of a filter are given by S = -0.6829, S = -0.1484 ± j0.5532, S = -0.4758 ± j0.4186 The locations for zeros are S = 0 ± j1.0515, S = 0 ± j1.7013, S = These poles and zeros are transformed to bandstop poles and zeros. (a) Find the frequency transformed bandstop poles and zeros when ϖ 1 = 6.6274e+003 rad/s and ϖ 2 = 2.3946e+004. (b) Find the digital poles and zeros when the sampling rate is 8000 Hz.
