Abstract: Rising and falling edges captured by a digital acquisition device appear to chatter on the X-axis by two or more sampling bin boundaries as live acquisition continually updates. This leads to a confusing display of limited usefulness. Averaging of multiple edges eliminates chatter while at the same time increases timing accuracy of the edges beyond the abilities of the base acquisition system.

A plurality of data acquisitions is stored in memory, and for each data acquisition, a number of rising and falling edges are identified. Each rising and falling edge is counted in each data acquisition. From these counted edges, an average waveform is calculated from the plurality of data acquisitions. The average waveform is displayed as an improved representation of the digital signal.
