ulab.numpy.fft – Frequency-domain functions
r (ulab.numpy.ndarray) – A 1-dimension array of values whose size is a power of 2
c (ulab.numpy.ndarray) – An optional 1-dimension array of values whose size is a power of 2, giving the complex part of the value
The real and complex parts of the FFT
Perform a Fast Fourier Transform from the time domain into the frequency domain
See also ulab.utils.spectrogram, which computes the magnitude of the fft, rather than separately returning its real and imaginary parts.
