Multi-dimensional signal processing for non-linear structural dynamics
Abstract
The objective of this paper is to present a non-linear analyser based on a multi-dimensional Fourier transform. The Winograd fast algorithm allows drastic reduction of algebraic operations. Window, calculations of higher order functions as welll as graphical representation of multivariate functions are also presented and discussed. Some applications in non-linear structural dynamics using this analyser show the versatility and possibilities of this instrument.
