| 内容記述 | Correlation techniques are used to measure the characterizing parameters of the wave propagation system. The traveling wave representation of a vibrating system is discussed. Delay times and amplitude coefficients are considered to be the characterizing parameters, not only in the nondispersive wave propagation system but also in the dispersive case, if group delay time is defined. Three kinds of correlation method, such as, the correlation envelope method, the squared signal correlation method and the M-sequence correlation method are proposed to measure the group delay time and wave intensity. The acoustic wave propagation as an example of nondispersive case and the flexural wave propagation as a dispersive case are described and typical measured correlation functions are illustrated. | |||||||
