9. Design a digital IIR filter with the following specifications: Filter type = bandpass filter Maximum loss in the passband = 1 dB Minimum loss in the stopband = 33 dB Lower stopband cutoff frequency = 1000 Hz Lower passband cutoff frequency = 1500 Hz Upper passband cutoff frequency = 2000 Hz Upper stopband cutoff frequency = 2500 Hz Sampling rate = 8000 Hz Approximation = Chebyshev type 2 Excess tolerance = stopband (a) Find the digital cutoff frequencies. (b) Find the prewarped cutoff frequencies. (c) Find the normalized cutoff frequencies. (d) Find the order n of the filter. Recalculate parameters if needed. (e) Find the poles and zeros of the normalized lowpass filter. (f) Find the poles and zeros of the frequency transformed filter. (g) Find the digital poles and zeros using bilinear transformation (h) Find the transfer function of the digital filter. Find the constant term. (j) Plot the magnitude response and the phase response. Find the losses at the cutoff frequencies.
