Academics : The Endeavour

My previous post said that all the familiar variations on Fourier transforms—Fourier series analysis and synthesis, Fourier transforms on the real line, discrete Fourier transforms, etc.—can be unified into a single theory. They’re ...

Academics / Mathematics : A Neighborhood of Infinity

Why another introduction to the Fourier transform?There are many elementary introductions to the discrete Fourier transform on the web. But this one is going to be a little different. I hope to motivate and demonstrate an applicatio...

Technology : Geeks are Sexy

The Fourier transform, named after Joseph Fourier, is a mathematical transform with many applications in physics and engineering. Very commonly it transforms a mathematical function of time, f(t), into a new function, sometimes deno...

Humor : Cool Infographics

Fast Fourier Transforms: A Study Guide from Tektronix is a great example of using data visualization and infographic design principles to visually explain the math behind their oscilloscopes. Most engineers don’t remember the comple...
