Pulse Dispersion and Pulse Velocity

Abstract

Any physically consistent setting up of a pulse problem should incorporate three basic components: a source of the perturbation, a medium of propagation and a receiver spatially separated from the source. To obtain a reproducible experiment one should eliminate all other sources of perturbations, and initiate the signal in the medium at rest at a certain moment in time. In this case the received signal would be the same any time neglecting the noise background in the source, medium and receiver.
