摘要

A laboratory experiment for undergraduate students in mathematics and physics is introduced. The experiment concentrates on dispersion in acoustic waveguides, The dispersion relation is measured for different propagation modes and its effect on the transmission of signals is examined, looking at it from several points of view, with the main focus on Fourier aspects. The distortion caused by single mode dispersion is explained in terms of the convolution relation between the input signals and the impulse response of the waveguides.
