We wish to use the Kaiser window method to design a symmetric real-valued FIR filter with zero phase that meets the following specifications:

This specification is to be met by applying the Kaiser window to the ideal real-valued impulse response associated with the ideal frequency response H_d(e^jω) given by

(a) What is the maximum value of δ that can be used to meet this specification? What is the corresponding value of β? Clearly explain your reasoning.

(b) What is the maximum value of that can be used to meet the specification? What is the corresponding value of M +1, the length of the impulse response? Clearly explain your reasoning.
