Fourier series is an infinite series of trigonometric functions that represent the periodic function. Also, Learn the Fourier series applications, periodic functions, formulas, and examples at BYJU'S.
Fourier series expansionsComplex coordinate stretching layersOptical grating waveguideWe study the Fourier series expansion method combined with complex coordinate stretching layers. In addition, we discuss the details of the parameters in the complex coordinate stretching layers, when the method is used in...
this formula is called an orthogonal expansion of f(x). If a function has an orthogonal expansion, we can represent it using just an array of coefficients such as ci (i = 1,2,…) in (2.7). The Fourier series expansion above is one of the representation methods that provide orthogonal ...

For most signals, the resulting Fourier series has an infinite number of terms and coincides point-wise with the signal. We will start with the general expansion that uses complex exponentials and from it obtain the sinusoidal form. Recall that a periodic signal x(t) is such that • it ...
To calculate Fourier expansion between two different intervals, we use the Fourier series formula which involves finding the coefficients of the sine and cosine terms. These coefficients are then used to construct the expanded function, which can be used to approximate the original function over the...
