If you can get hold of it, the book. The easiest way would be to record a bunch of points as we rotate, and average them to find their midpoint: This form is normally called the inverse DFT, which is confusing, but apparently the difference between the DFT and IDFT is a matter of convention, and can depend on the application. Brigham It will tell you all you ever want to know about FFT, written in an almost casual style. The Fourier Transform and its Applications - free book at E-Books Directory - download here. Today I'll just show you two of the most essential Fourier transform pairs in signal processing applications. I think many people know that "the Fourier transform of a Gaussian is a Gaussian", but the [Duoandikoetxea says that this is the approach taken by Norbert Wiener in "The Fourier Integral and Certain of its Applications".] Why do these Hermite-Gauss functions show up in the physical situations mentioned earlier? Here's a cosine signal: Plots corrected December 14 thanks to help from Mark Andrews. The Fourier transform is a linear operator on a space of functions, so it has eigenvectors and eigenvalues: functions who are their own Fourier transform. Eventually I learned that I needed something called a Fourier transform, so I took a trip to the library and looked it up (which is what we had to do back in those days).
