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 ...

Although examples have been given showing that the spherical average of the Fourier transform cannot decay always too fast, they usually do not exhibit a single measure decaying sufficiently slow on ...

The hardware bit-reverse and linear-address generator in Fig 1a scrambles a time-domain digital N-sample record. The circuit is primarily meant to scramble data before taking a real-time butterfly FFT ...
