        scale : {'default', 'linear', 'dB'}
            The scaling of the values in the *spec*.  'linear' is no scaling.
            'dB' returns the values in dB scale, i.e., the dB amplitude
            (20 * log10). 'default' is 'linear'.

        Fc : int, default: 0
            The center frequency of *x*, which offsets the x extents of the
            plot to reflect the frequency range used when a signal is acquired
            and then filtered and downsampled to baseband.

        Returns
        -------
        spectrum : 1-D array
            The values for the magnitude spectrum before scaling (real valued).

        freqs : 1-D array
            The frequencies corresponding to the elements in *spectrum*.

        line : `~matplotlib.lines.Line2D`
            The line created by this function.
