Abstract
A criterion for the quantitative estimation of the signal spectrum change is analyzed. The model of pressure piezoconverter output signal shows the applicability of this criterion to detect the output signal spectrum change and to localize such changes.
Keywords
signal spectrum, quantitative estimation of signal spectrum change, pressure piezoconverter signal
