The default value for step is 1. As an example, let's consider the np.arange () method that generates a NumPy array of all the integers from 0 to 9 (inclusive): Webbnumpy.fft.fftfreq# fft. fftfreq (n, d = 1.0) [source] # Return the Discrete Fourier Transform sample frequencies. The returned float array f contains the frequency bin centers in cycles per unit of the sample spacing (with zero at the start). For instance, if the sample spacing is in seconds, then the frequency unit is cycles/second. rsiam off audio
