Assignment Help Electrical Engineering

Reference no: EM13264972

Design a highpass IIR filter with the following specifications:
Filter order= 4, Chebyshev type
Ripple on the passband =1 dB
Cut-off frequency=1500 Hz
Sampling rate =8000 Hz
Design using the bilinear z-transform design method

Print the highpass IIR filter coefficients and plot the frequency responses using MATLAB.

MATLAB>>freqz(bHP,aHP,512,8000);
axis([0 4000 -40 1]);% sampling rate=8000 Hz

Label and print your graph.

What are the filter gains for the stopband at the cut-off frequency and 500 Hz, and passband at 3000 Hz based on the plot of the magnitude frequency response?
