For restoration of time-domain signals, an
estimate of the instantaneous magnitude spectrum is combined with the
phase of the noisy signal, and then transformed via an inverse discrete
Fourier transform to the time domain. In terms of comput

The magnitude
and power spectrum are non-negative variables, and any negative estimates
of these variables should be mapped into non-negative values. This nonlinear rectification process distorts the distribution of the restored signal.
