WebJul 30, 2024 · Answers (2) The advantage of nufft is that it allows you to compute the FFT of non-uniformly sampled signals. You cannot do this with fft. If your signals are uniformly sampled, then there is no need to use nufft. fft and nufft both are fast ways to calculate Discrete Fourier Transform of any signal. The only disadvantage of fft over nufft is ... WebIt’s done by adding together cuFFTDx operators to create an FFT description. The correctness of this type is evaluated at compile time. A well-defined FFT must include the problem size, the precision used (float, double, etc.), the type of operation (complex-to-complex, real-to-complex, etc.), and its direction (forward, or inverse).
