Abstract
The work described is part of a programme exploring the utility of digital signal-processing techniques for studying certain aspects of the behaviour of water-waves. When such studies are undertaken in a closed wave-tank reflections from the boundaries can be troublesome. To this end a cepstral analysis has been attempted on wave-height measurements to locate and assess these reflections. The auto-regressive power-spectral estimate has been used to obtain the cepstrum with some success and the results are compared with those obtained by more conventional data processing methods.
