As telecommunication engineer in telecommunication company, you are required to design suitable IIR filter using BUTTERWORTH filter method to minimize the Gaussian White noises in telecommunication device. The design filter should meet the following specifications. 1) 11) 111) Passband frequency: 1.5 kHz Stopband frequency: 0.65 kHz Stop attenuation: 45 dB Passband ripple: 2 dB Sampling frequency: 5.5 kHz Construct MATLAB program to determine the filter order/length, filter coefficients, filter responses, transfer function of the system and pole-zero (unit circle). Plot the filter response, poles-zeros plot. Filter Coefficients (Impulse response). Provide the manual calculation as well. [MATLAB command: butter, chebyl, buttord, chebylord, tf, zplane, residuez & freqz] Determine the Causality and Stability of the system. Next, repeat step i) and ii) using CHEBYSHEV Type I filter method.
