AWGN is a very basic noise model commonly used in the communication system, signal processing, and information theory to imitate the effect of random processes that occur in nature.CSE486, Penn State Robert Collins Lecture 4: Smoothing Related text is T&V Section 2.3.3 and Chapter 3The quality of a signal is often expressed quantitatively as the signal-to-noise ratio (S/N ratio), which is the ratio of the true underlying signal amplitude (e.g. the average amplitude or the peak height) to the standard deviation of the noise. Thus the S/N ratio of the spectrum in Figure 1 is about 0.08/0.001 = 80, and the signal in Figure 3 has a S/N ratio of 1.0/0.2 = 5.or software compressors. Adjustment to the matlab code could be made to make the controls more understandable to audio practitioners. 1.
