Image text transcribed for accessibility: Suppose we have an even-symmetric FIR filter h|n| of length 2L + 1, i.e., h[n] = 0 for |n| > L. h[n] = h[-n]. The frequency response H(ej omega), i.e., the DTFT of h|n|, is plotted over -pi omega pi in Figure P7.24. Normalized frequency omega Figure P7.24 What can be inferred from Figure P7.24 about the possible range of values of L? Clearly explain the reason(s) for your answer. Do not make any assumptions about the design procedure that might have been used to obtain h[n].
