Why is the Peak Value and Crest Factor Unstable?
- The WT's sampling speed is from a few dozen kHz to several hundred kHz. The peak values of signals whose peaks are more narrow than this may not be captured by the WT. On the other hand, if it is a repeating, stable peak signal, the WT has a good chance of capturing it.
- For rising peak signals having components that are higher than the WT's bandwidth, the peak is attenuated by analog bandwidth restriction. Therefore the peak value may not be captured by the WT.
