WebThe fast Fourier transform (FFT) is a common and efficient method to calculate the discrete Fourier transform (DFT). The FFT core computes the FFT using the 2-parallel radix-22 feedforward algorithm. The FFT core takes in a complex data vector as input and outputs the complex vector in the natural order in the frequency domain. WebMay 17, 2024 · radix_3_fft.
