A method of detecting the position of a wavefront in a time-varying signal corresponding to an event is disclosed. According to one aspect, the method includes digitizing a signal received by a detector to produce a working signal, filtering the working signal N4 times with a band-pass filter to obtain N4 filtered working signals with different pass-bands, detecting a peak of the N4 filtered working signals to detect the position of a first wavefront as a function of time of occurrence. The N4 points are plotted such that an ordinate is one of the times of occurrence and an abscissa is the width of the associated band. An exponential asymptote that fits a maximum number of the N4 points is applied, and the position of the wavefront is determined as the ordinate of the point that has the maximum abscissa and substantially fits the exponential asymptote. |
