Question
What is fourier series? What are the three important classes of fourier series methods available?
Solution
A Fourier series is a mathematical tool used in analysis, which breaks down any periodic function or periodic signal into the sum of a (possibly infinite) set of simple oscillating functions, namely sines and cosines. It is named after Jean-Baptiste Joseph Fourier, who introduced the series in his work on heat transfer.
The three important classes of Fourier series methods available are:
-
Trigonometric Fourier Series: This method represents a periodic function as a sum of sine and cosine functions. It is the most common form of Fourier series.
-
Complex Fourier Series: This method represents a periodic function as a sum of complex exponentials. It is often used in signal processing and control systems.
-
Half-Range Fourier Series: This method represents a function defined over a finite interval as a sum of sine and cosine functions. It is often used in solving problems in physics and engineering.
