The rectangular function (or square-pulse) is commonly used in signal processing applications. The Fourier transform of the rectangular function is the normalized sinc function given by: sinc() sin(a) Write a function normsinc that returns sincx). Your function must: 1. Calculate sinc(x) for each element of the input. If the input is a 1-by-4 vector, the output is also a 1-by-4. 2. Return the value 1 when the input is 0, which is the limiting value of sinc as -0.
