SpletShort-time FFT expand all in page Description The dsp.STFT object computes the short-time Fourier transform (STFT) of the time-domain input signal. The object accepts frames of time-domain data, buffers them to the desired window length and overlap length, multiplies the samples by the window, and then performs FFT on the buffered windows. SpletShort-time Fourier transform (STFT). The STFT represents a signal in the time-frequency domain by computing discrete Fourier transforms (DFT) over short overlapping windows. This function returns a complex-valued matrix D such that np.abs (D [..., f, t]) is the magnitude of frequency bin f at frame t, and Splet15. apr. 2016 · FFT assumes periodicity.
