Modal and Spectrum Analysis

This book attemps to unify multivariate time series analysis, modal analysis and spectrum analysis, to provide an unparalleled data processing and modelling tool. It provides a systematic, rational approach that yields far more accurate results. Instead of guessing the form of the model based on necessarily inadequate a-piori information, the book outlines a procedure that yields the models directly from real data - experimental or operational. The models then provide all the information desired from the usual modal analysis and spectrum analysis.
