        Parameters
        ----------
        out : {None, FrequencySeries}
            Write the decompressed waveform to the given frequency series. The
            decompressed waveform will have the same `delta_f` as `out`.
            Either this or `df` must be provided.
        df : {None, float}
            Decompress the waveform such that its `delta_f` has the given
            value. Either this or `out` must be provided.
        f_lower : {None, float}
            The starting frequency at which to decompress the waveform. Cannot
            be less than the minimum frequency in `sample_points`. If `None`
            provided, will default to the minimum frequency in `sample_points`.
        interpolation : {None, str}
            The interpolation to use for decompressing the waveform. If `None`
            provided, will default to `self.interpolation`.

        Returns
        -------
        FrequencySeries
            The decompressed waveform.
