2. Filter Desgn with some algorithms This exercise uses speksitIIR.m function from Mycourses. The function has to be in the same folder as this skript to work. You can write 'help speksitIIR' to Command Window to get information about speksitIIR function. Sampling frequency in both sections is 48000 Hz. Use legend() to name each magnitude response clearly. Helpful functions: butter, buttord, chebl, cheblord, ellip, ellipord, freqz a) Design digital minimum order (lowest possible order) I) Butterworth, II) Chebyshev 1 and III) Elliptic high-pass filters that fulfill specs drawn on the figure(1) and plot them to figure(1). b) Design digital minimum order (lowest possible order) I) Butterworth, II) Chebyshev 1, III) and Elliptic band-pass filters that fulfill specs drawn on the figure(2) and plot them to figure(1). c) What are the orders of each filters and what differences: butterworth, chebyshev 1 and elliptic filter have? 2.
