Intro. to Signal Processing:Signals and noise

The 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.
