to implement a notch filter
which is useful for removing one frequency component while leaving other frequency
components undisturbed.
The notch filter will be implemented from the cascade of two
simpler filters whose Frequency Response magnitudes are shown in Figure F1:
Figure F1
a)
Start by designing two filters, one to implement the FIR Filter and the other to
implement the Feedback Filter given in Figure F1.
