Envelope modelling of impulse response functions of systems having a high modal density

Abstract

The description of the transmission of a transient excitation through a complicated (but linear) channel is expressible as a convolution (by a 'complicated' system we mean one whose frequency response exhibits a high nodal density) The basic convolution expression (or its frequency domain equivalent) is often not convenient for investigation of a particular… (More)
