9.1.4 Waterfall graph

The Waterfall graph module presents the power spectra for the entire time-length of the framework.

The Waterfall graph module computes the power spectra with an adjustable frequency resolution.

Each power spectrum is presented in a three dimensional graph along a time axis. As well as the

numerical amplitude scale, a color scale is employed to help in visualizing the high and low levels of

the power spectrum amplitudes. The three dimensional graph can be rotated, zoomed and moved.

The next figure presents the waterfall interface.

At any time, the computation parameters can be changed and the recompute button can be used to

update the results.

The next table explains the computation parameters:

1 2 ... 30 31 32 33 34 35 36 37 38 39 40 ... 61 62
