Log Squared Plot
Figure
2 shows the Log Squared Plot of the data in Figure 1. This plot
is obtained by computing the logarithm of squared time data.

Cumulative Energy Plot
Figure
3 shows the beginning of a Room Impulse Response. Figure
4 shows the Cumulative
Energy Plot
of the data in Figure 3. This plot is obtained by computing
the integral
of squared time data.
