We wish to use the Kaiser window method to design a discrete-time filter with generalized linear phase that meets specifications of the following form:
(a) Determine the minimum length (M + 1) of the impulse response and the value of the Kaiser window parameter β for a filter that meets the preceding specifications.
(b) What is the delay of the filter?
(c) Determine the ideal impulse response hd [n] to which the Kaiser window should be applied
