Such as, when the waveform pace of change of data signal is very fast, the n of big numerical value can be selected, conversely, numeral letter
Number waveform pace of change it is slower when, then select fractional value n.
Secondly, above-mentioned multiple data signals are calculated to obtained RV respectively and contrasted, calculation formula is such as
(6)。
Wherein, RV1 is the RV of data signal 1, and RV2 is the RV of data signal 2, then RVV is
