The Frequency Response Function (FRF) is a complex valued function defined over a frequency range. The process of identifying parameters from this type of measurement is commonly called curve fitting or parameter estimation.
Rational Fraction Polynomial method (RFP method) perform curve fitting on these measurements (FRFs) to identify the modal parameters (natural frequencies, damping ratios, mode shape) of the predominant modes of vibration of the structure, but it can also be used for identifying poles, zeros and resonances of the combined electro-mechanical-acoustic system.
