I have been pounding my head on understanding Fourier series as it applies to *Discrete Signal Processing*, But I have spent so many days and still am having major problem on understanding this.....

I really think that my number one problem is that I do not know how to solve the Fourier Series.... So, I would like anybody that has any knowledge on the topic to please help me out, I think what I really need is seeing it from another persons point of view..

I would really appreciate any quick reply to this question......
Thanks to all

Hi,
i had the problem advise you to take an example and follow the resolution.
it s all about reasoning.
this is http://www.cse.salford.ac.uk/profiles/gsmcdonald/H-Tutorials/Fourier-series-tutorial.pdf
hope help you

Here's a good article to read on understanding the fourier transform.

This is broken out by how the function works

First of all do you get the concept that you can synthesize waveforms with combinations of sine, cosine and a DC. Thats where it starts. The Discrete Signal Processing is just an adaptation of the continuous signal processing.

The person didn't really describe where the divergence is, beginning, middle, end. Perhaps at the end because DSP is after basic Fourier Transforms.

Fourier Analysis is basically used to determine the different frequencies & their harmonics (i.e multiples of the fundamental frequencies) present in the signal. once this frequencies are determined the later job is to filter out the frequency which is not needed (i.e noise). That is fourier analysis, please refer some books you will understand!

Topic summary

The discussion addresses difficulties in understanding and solving Fourier series within Discrete Signal Processing (DSP). Key advice includes working through step-by-step examples to grasp the reasoning behind Fourier series solutions. Fundamental concepts highlighted are the synthesis of waveforms using sine, cosine, and DC components, and the adaptation of continuous Fourier transforms to discrete signals. Fourier analysis is explained as a method to identify fundamental frequencies and their harmonics in signals, enabling filtering of unwanted noise. Recommended resources include a detailed tutorial PDF on Fourier series and an article explaining the Fourier transform, both aimed at clarifying the underlying principles and practical application in DSP.
