BASICS OF FOURIER SERIES

INTRODUCTION:                                                Fig.1 periodic square wave Fourier series are used in the analysis of periodic functions. Many of the phenomena studied in engineering and science are periodic in nature eg. The current and voltage in an alternating current circuit. These periodic functions can be analysed into their constituent components (fundamentals and harmonics) by a process called Fourier analysis . We are aiming to find an approximation using trigonometric functions for various square, saw tooth, etc. waveforms that occur in electronics. We do this by adding more and more trigonometric functions together. The sum of these special trigonometric functions is called the Fourier series . Periodic functions ...
