Abstract: In this paper, we investigate the effect of fixed-point arithmetics with limited precision for different fast Fourier transform (FFT) algorithms. A matrix ...

Input real-valued data and get the DFT output. Supports audio files and CSV file or string inputs with a variety of output formats. Also supports FFT algorithms. Standard output to terminal. Text file ...

Abstract: This brief presents a novel architecture for memory-based fast Fourier transform (FFT) computation for real-valued signals based on radix-2 decimation-in-frequency algorithm. A superior ...
