<p>A digital oscilloscope processes digitized input waveform data sequences according to a user defined mathematical expression to compute a processed waveform data sequence controlling a periodically updated waveform display on a screen. The waveform data is computed during equivalent time computation passes during each of which pass every Nth data of the waveform data sequence is computed. The first waveform data computed during each pass is selected in a pseudorandom fashion such that each data of the waveform data sequence is computed once every N computation passes. The value of N is suitably chosen so that the duration of each pass is substantially equal to the period between waveform display updates.</p> |
