Fourier transformation sinc

Webhas a Fourier transform: X(jf)=4sinc(4πf) This can be found using the Table of Fourier Transforms. We can use MATLAB to plot this transform. MATLAB has a built-in sinc function. However, the definition of the MATLAB sinc function is slightly different than the one used in class and on the Fourier transform table. In MATLAB: sinc(x)= sin(πx) πx WebMar 17, 2024 · The Fourier transform of the normalized sinc function is the rectangular function with no scaling. This function is fundamental in the concept of reconstructing the original continuous bandlimited signal from uniformly spaced samples of that signal. Reciprocal Gamma function.
