Fourier series And Fourier Transform

Abstract

An introduction to Fourier Series and Fourier Transform is the topic of this paper. It deals with what a Fourier Series means and what it represents. The general form of a Fourier Series with a provision for specific substitution has also been mentioned. The paper also includes a brief overview of Fourier Transform. The use of Fourier Transform to convert a time domain function into a frequency domain equivalent has also been shown. A method of converting the continuous Fourier Transform into a discrete form and thus obtaining the Discrete Fourier Transform has also been discussed. A few practical life application of Fourier analysis have been stated.
