Abstract
A method and system for analyzing a signal waveform that comprises digitally sampling a signal at a periodic sampling interval, and accumulating a count of samples of the signal at a given logic level relative to a threshold value over a given period. The threshold value is stepped through a series of values while the accumulating of samples is repeated at a series of different clock offsets. The accumulated counts permit a statistical distribution of the signal waveform to be determined. A signal density can also be calculated by determining the difference between the count of adjacent samples at successive threshold values.
