A first order analog low pass
Butterworth filter has a -3dB frequency of 2.5kHz and a DC gain of unity.
a. Use a bilinear transformation to find a digital filter H(z) to match the analog filter for a sampling rate of 8kHz with and without prewarping.
b. Plot the magnitude response for both filters obtained in (a)

/in Feeds /by Munene davidNeed help with this question
A pass band filter has a center frequency of 5k Hz. Its
maximum gain is 0 dB and its pass band edges lie at -0.5dB, 1.6 kHz apart. Transition widths are 400 Hz , and the stop band attenuation is 35 dB. Choose and order for the Chebyshev Type 1 filter that satisfies these specification for a 15 kHz sampling rate.
