Efficiency of the TDAM and other data-compression methods: a new efficiency index

Abstract

In a recent paper, the time domain analysis method (TDAM) was described. Its experimental results are now compared with those obtained from two other and distinct methods. This comparison demonstrates high efficiency of the TDAM in all the studied cases. On the other hand, the three methods present an important common feature: the memory size necessary for the final data depends logically on the prefixed error and the signal, but it depends very little on the number of samples taken from a given waveform. This final memory size is then proposed as a new efficiency parameter, at least for the methods which perform this feature.
