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 ...

Low-Power High-Speed Radix-2 DIT FFT Suitable for AAC/DRA Audio Decoding

Abstract: In this paper, an implementation of low-power, high-speed radix-2 DIT (decimation-in-time) FFT suitable for AAC/DRA audio decoding is presented. For low-power and high-speed considerations, ...
