Introduction
Fourier analysis is a field of mathematics that studies how general functions can be approximated or represented by the addition of simple trigonometric functions. Fourier analysis is named after a man who proved that representing a mathematical function in the form of a sum of a trigonometric function simplifies the inquiry into heat propagation. Joseph Fourier envisioned the Fourier series, a concept from which Fourier analysis grew. Presently, vast spectrums of mathematics involve Fourier analysis as a subject. The subject spans through the field of engineering and sciences. In these two fields, Fourier analysis involves the process through which a function is decomposed into simpler functions. The ...
