Fourier transform as a function of frequency ω versus Fourier transform as a function of frequency f

A slecture by ECE student JOE BLO

Partly based on the ECE438 Fall 2014 lecture material of Prof. Mireille Boutin.



Introduction

In my slecture I will explain Fourier transform as a function of frequency ω versus Fourier transform as a function of frequency f (in hertz).

Theory

  • First let's review formulas we used in 301
(info) CT Fourier Transform $ \mathcal{X}(\omega)=\mathcal{F}(x(t))=\int_{-\infty}^{\infty} x(t) e^{-i\omega t} dt $
(info) Inverse DT Fourier Transform $ \, x(t)=\mathcal{F}^{-1}(\mathcal{X}(\omega))=\frac{1}{2\pi} \int_{-\infty}^{\infty}\mathcal{X}(\omega)e^{i\omega t} d \omega\, $


Example

  1. THIS IS THE FIRST ITEM
  2. THIS IS THE SECONF ITEM

Post your slecture material here. Guidelines:

  • If you wish to post your slecture anonymously, please contact your instructor to get an anonymous login. Otherwise, you will be identifiable through your Purdue CAREER account, and thus you will NOT be anonymous.
  • Rephrase the material in your own way, in your own words, based on Prof. Boutin's lecture material.
  • Feel free to add your own examples or your own material.
  • Focus on the clarity of your explanation. It must be clear, easily understandable.
  • Type text using wikitext markup language. Do not post a pdf. Do not upload a word file.
  • Type all equations using latex code between <math> </math> tags.
  • You may include graphs, pictures, animated graphics, etc.
  • You may include links to other Project Rhea pages.

IMPORTANT: DO NOT PLAGIARIZE. If you use other material than Prof. Boutin's lecture material, you must cite your sources. Do not copy text word for word from another source; rephrase everything using your own words. Similarly for graphs, illustrations, pictures, etc. Make your own! Do not copy them from other sources.
