Chirp wavelet PSD
-----------------
Figure 10.28

A wavelet PSD of the ten-parameter chirp signal similar to that analyzed in
figure 10.27. Here, the signal with an amplitude of A = 0.8 is sampled in
4096 evenly spaced bins, and with Gaussian noise with sigma = 1. The
two-dimensional wavelet PSD easily recovers the increase of characteristic
chirp frequency with time.
