Overview of Analysing Your Spectra

PRAP 2.1 allows resonance spectra to be analysed in more then one way. This is different from PRAP 1.6 and earlier versions where each resonance mode could typically be analysed in only one way. A new feature utilised by most of the analysis modules is the PRAP non-linear regression engine. This allows material properties of each resonance mode to be fitted to measured resonance spectra using least-squares fitting.

In addition to new support for non-linear regression, the traditional resonance modes have new routines for determining results for the minimum norm. The routines for minimising the norm are also utilised in new routines for automatically analysing the resonance spectra. See the descriptions of analysing each mode for details.
