DIT and DIF algorithms for FFT Implementation

DIT (Decimation in Time) and DIF (Decimation in Frequency) are two common algorithms used for calculating the Fast Fourier Transform (FFT) of a discrete signal. These algorithms are efficient and can ...

Canonic real-valued FFT structures

Abstract: An N-point FFT processes N complex signals to compute N output complex signals using decimation-in-time (DIT) or decimation-in-frequency (DIF) approach. The FFT makes use of n = log 2 N ...
