Determining the Mean, Standard Deviation, and p-p of the Trace
Determining the Mean, Standard Deviation, and p-p of the
Trace
You can easily determine the statistics data for a trace (mean, standard deviation, and
peak-to-peak). Figure 6-15 and Table 6-3 show the definitions for the statistics data
elements.
