Question: M-File for asinc Write a MATLAB function as inc (w, L) that will evaluate asinc (w, L) on a frequency grid directly from formula (1-3). The function should have two inputs: a length L and a vector of frequencies w. It must check for division by zero as happens for w = 0. Directly evaluate the "a liased sine" formula (1-2) for the DTFT of a pulse. Plot the magnitude and save this plot for comparison to the result obtained with dtft.
