Description: 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.
The processing distortion becomes more noticeable as the signal-to-noise
ratio decreases. In this chapter, we study spectral subtraction, and the
different methods of reducing and removing the processing distortions.
