QUESTION)
a) Design a low-pass IIR filter using the Butterworth technique.
In the passband, magnitude response of the filter can have a ripple
of 1dB and stopband gain should be -45dB. Passband frequency is
0.1π and stopband frequency is 0.6π.
b) Compute the output y(n) for n=1:1000 when the input is x(n) =
cos(πn/4)+ sin(5πn/2)+2u(n) using the filter in part-a using
matlab.
c) Design an FIR filter with the Kaiser window technique with
the same specs in part-a.
QUESTION-2) a) Design a low-pass IIR filter using the Butterworth technique. In the passband, magnitude response of the filter can have a ripple of 1dB, and stopband gain should be -45dB. Passband frequency is 0.1 and stopband frequency is 0.67. b) Compute the output y(n) for n=1:1000 when the input is x(n) = cos(лn/4) + sin(5/2) + 2u(n) using the filter in part-a using MATLAB. c) Design an FIR filter with the Kaiser window technique with the same specs in part-a.
