Compute approximations to Fourier transforms of continuous-time signals with finite discrete time methods. Take advanced courses in signal processing (image, speech, audio, etc.), communications, ...

The previous sample, Implementation of Fast Fourier Transform for Image Processing in DirectX 10, implements the UAV technique using pixel shaders.

To form an image of the sky, one takes the inverse 2D Fourier Transform of the correlator output. However, for virtually all radio interferometers, the distribution of projected baselines on the ...
