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 Fast Fourier Transform (FFT) is an implementation of the Discrete Fourier Transform (DFT) using a divide-and-conquer approach. A DFT can transform any discrete signal, such as an image, to and ...

Comprehensive introduction to analysis of continuous and discrete-time signals and systems. Linear time-invariant systems, convolution; Fourier series representations of periodic signals; Continuous ...

Fourier transforms are one of the most important algorithms in math, and help our electronics handle visual and audio signals in a sophisticated way.

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 ...

The algorithm uses efficient operations based on discrete Fourier transforms.
