Digital signal processing (DSP) software development. Abstract. Discrete Fourier transform. Relationship between the (continuous) Fourier transform and the discrete Fourier transform.

Discrete Fourier transform

Left column: A continuous function (top) and its Fourier transform (bottom). Center-left column:Periodic summation of the original function (top). Fourier transform (bottom) is zero except at discrete points. Discrete Fourier Transform Tutorial. HINT: If program is too big for screen click mouse in program then push "CTRL" and spin mouse wheel at the same time... or push F11 for full screen.

Discrete Fourier Transform Tutorial

Learn the Discrete Fourier Transform by creating your own function in a flash program and then going through the steps to generate a 16 point DFT on the function you created. If you are confused about complex numbers and how they combine to form real sinusoids, you might want to look over The complex Fourier Series tutorial on this site first, or look at the four programs that demonstrate complex numbers.
