Fully understand the properties of Fourier transform and wavelet (6)--Fourier series expansion function term series

In the previous section we introduced the concept of the series of function items, which we discuss the properties of the series of function items. Fourier series is a series of function items (trigonometric functions), in essence, an image (or a set of signals) is a function, we study the Fourier transform of the image, is to explore how to use the function of the triangle function to expand the image. Therefore, it is very necessary to discuss the properties of the series of function items if we want to fully understand the Fourier transform. On this basis, we will introduce the concept of Fourier series.

If you are not familiar with the underlying issues covered in this article, it is recommended that you read the sections earlier in this article. Hope that the reader can accumulate, consolidate the foundation.
