Because the FFT is inherently a block-oriented algorithm, the FFT operates most efficiently when quick access to all input and output samples is supported by a freely-addressable RAM. However, this ...

So, with suitable hardware multiplexing schemes, this same engine can be used to handle four streams of input data instead of just one. For example, in building a dual-channel software-radio mezzanine ...

This example processes framebuffer data from the Mozilla Audio Data API MozAudioAvailable event. The Fast Fourier Transform algorithm is used to obtain audio frequency levels which are then ...

Cooley and Tukey’s Fast Fourier transform (FFT) represented a major breakthrough that paved the way for many of the electronic conveniences we take for granted today. Without the FFT providing an ...

The G-Logger offers 16-bit data acquisition, with data rates of 1 to 10k samples per second and per axis, through each of its available input channels.

Several algorithms for efficiently evaluating trigonometric polynomials at irregularly spaced points are presented and analyzed. The algorithms can be viewed as approximate generalizations of the fast ...
