1. We will use the audio signal provided by MATLAB, the file handel mat.' The audio signal is sampled at a rate of 8192Hz The audio equalizer will divide the audio bandwidth into 5 equal bands as follows: 2. 250Hz 500Hz band 1 band 2; 250 500 1000 2000 1000Hz band 3; 2000Hz band 4 4096Hz band 5 Assume tha passband and stopband edge frequencies are +55 or -55Hz away from the cutoff frequencies. 3. 4. Design the 5 IR 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 1. We will use the audio signal provided by MATLAB, the file handel mat.'
