Matlab scripts to generate truncated fourier series of a function and analyse the function in time as well as in frequency domain. The variable named choice captures the analysis domain i.e time or ...

A Matlab script to calculate the filtering/processing performed on an optical image by an optical element (such as a thin metasurface) characterized by angle-dependent vectorial transfer functions.

Abstract: Singularity functions are an important topic in undergraduate studies covered primarily in signal processing. Some of those functions are the step function, the ramp function and the ...

Title: Integers and Delta Functions: Convolution Isomorphism, Fourier Duality, and the Poisson Summation Formula (Revised Edition with Supplements) Note: This manuscript is a mathematically and ...

Abstract: New formulas for the two-dimensional Fourier transform of functions with polygonal support and linear amplitude variation are derived from the corresponding formula for a constant function.
