Figure 3. Left: 60 sec of the synthetic signal (top), 60 sec of the synthetic signal
+ noise (maximum amplitude equal to 0.5 the maximum amplitude of the
signal, middle), 60 sec of synthetic signal + noise (maximum amplitude
equal to 1.0 the maximum amplitude of the signal). Center: the filtered signals.
Right: spectral ratio between the spectra of the signal + 0.5 noise and the
spectra of the signal + 1.0 noise.
