Design low-boost shelving and low-cut shelving filters, MATLAB

1. Design your own low-boost shelving filter which can boost the low frequency of given music signal. After designing filter, apply the filter to the original music signal and observe the result. Include following plots. A. Magnitude and phase plot of your filter. B. Magnitude plot of original signal C. Magnitude plot of filtered signal 2. Design your own low-cut shelving filter which can cut the low frequency of given music signal. For the problem 2, also include same plots as above. 3. Design your low-boost shelving filter and low-cut shelving filter to have noticeablly different sound. Compare the sounds of two music signals after filtering, and explain the difference in sounds briefly.
