 note = {The group delay time is defined for the dispersive wave propagation system. It is the time which is required for the envelope of the narrow band input signal to travel through the system. Three methods of detecting the group delay time by correlation techniques were developed and the experiments were performed in flexural wave propagation system., 資料番号: SA2400626000},
