Abstract
The invention is a method for accumulating and displaying digital waveform data, representing the behavior over time of an electrical signal that includes the steps of: repeatedly acquiring and digitizing (10) waveform data during a first set of time intervals, repeatedly acquiring and digitizing (10) waveform data during a second set of time intervals, the second set of time intervals alternating with the first set of time intervals, during each one of the time intervals in the first set of time intervals, ORing (83) each acquired and digitized waveform together to produce first composite waveforms, during each one of the time intervals in the second set of time intervals, ORing (86) each acquired and digitized waveform together to produce second composite waveforms, displaying (81,84) each first composite waveform during a next occurring time interval in the second set of time intervals, and displaying (81,84) each second composite waveform during a next occurring time interval in the first set of time intervals. In a preferred embodiment, the ORing process is qualified on a pixel-by-pixel basis dependent on the results of a comparison between a randomly generated number and a pr…
