Unformatted text preview: S = 0.1049 j0.9580, S = 0.2532 j0.3968 The locations for zeros are S = , S = , S = , S = . These poles and zeros are transformed to bandstop poles and zeros. (a) Find the frequency transformed bandstop poles and zeros when 1 = 6.6274e+003 rad/s and 2 = 2.3946e+004. (b) Find the digital poles and zeros when the sampling rate is 8000 Hz. (c) Find the constant term b such that 2 max . z ) z ( H a 05 1 10= = 4. The specifications of a lowpass IIR filter are: Maximum loss in the passband = 2 dB Minimum loss in the stopband = 55 dB Passband cutoff frequency = 1500 Hz Stopband cutoff frequency = 2000 Hz Sampling rate = 8000 Hz Find the order n and the normalized analog pole and zero locations when the following approximations are used: (a) Butterworth (b) Chebyshev Type I (c) Chebyshev Type II (d) Elliptic...
