Abstract :
The temporal quantisation process inherent to certain waveform acquisition systems is examined and quantified. It is shown that increasing sample density (oversampling) is markedly more effective than signal averaging in reducing the influence of this impairment and that timebase quantisation resolution requirements usually exceed those for signal amplitude, although signal averaging can ameliorate this situation.
