THE RECONSTRUCTION OF WAVEFORMS OF IMPULSIVE STRAIN OCCURING IN AN ELASTIC BAR BY MEANS OF DECONVOLUTION IN THE FREQUENCY DOMAIN<br />
Journal Title: Metrology and Measurement Systems - Year 2007, Vol 14, Issue 2
Abstract
The paper presents a method of reconstruction of impulsive strain waveforms based on deconvolution in the frequency domain and the spectral transmittance of the bar, which was determined experimentally and given in an analytic form. A regularization of the deconvolution is obtained by means of limiting the frequency band of the inversion filter. In this method the one-point or the two-point measurement of strain waves in an elastic bar can be utilized.
