抄録

An attempt is made to restore the original pulse forms from dispersed wave trains by using group velocity data in place of phase velocity data. For a given period, the group velocity is obtained, eventually, by usual method to interpolate group velocities of adjacent peaks of dispersed train, but the validity of the method is interpreted in slightly different way from the usual one.<br>Calculations are made for fictious dipersed train whose original form is known and for actually recorded data whose original form is unknown. The estimated pulse is of a form not completely free from uncertainties, but may be utilized to check an assumed source mechanism.
