MATLAB:Statistics Assignment

1.

The file RodrigoA.mat stored in the Experiment 3 area in Blackboard containstwo variables: sA is a short clip of music with two strong tones centred at 300 Hzsuperimposed on top of it, and fs is its sampling frequency. The tones can besuppressed by filtering sA with a bandstop filter with the following specification.

Design the above filter using Kaiser windows in FDAtool. Demonstrate your design iseffective by playing back the filtered signal. Plot also the magnitude spectrum of sA, before and after filtering.

2.As discussed, FDAtool does not return the?of the Kaiser window. To fill this gap, we wrote the function Kaiser_BP_Design. Modify this function (available fromBlackboard) to design the bandstop filter specified in Question 1 above. Call the newfunction Kaiser_BS_Design. What is the?of the filter? Does your design matchesthe FDAtool design
