Question

1. We will use the audio signal provided by MATLAB, the file 'handel.mat'. The audio signal is sampled at a rate of 8192Hz 2. The audio equalizer will divide the audio bandwidth into 5 equal bands as follows: 0 250 250Hz 500Hz band 1 band 2; 500 1000Hz band 3; 1000 2000Hz band 4 2000 4096Hz band 5 3. Assume tha passband and stopband edge frequencies are \pm 55Hz away from the cutoff frequencies. 4. Design the 5 IIR filters as Butterworth filters using MATLAB functions. Assume that the band edge frequencies given in the specification are the cut-off frequencies of the respective filters. What are the digital frequencies that correspond to each of the edge frequencies?

cutoff frequencies.
4. Design the 5 IIR filters as Butterworth filters using MATLAB functions. Assume that
the band edge frequencies given in the specification are the cut-off frequencies of the
respective filters. What are the digital frequencies that correspond to each of the edge
frequencies?
