  • Process and machine for signal waveform analysis
    Patent number: 6137283
    Abstract: Highly accurate time interval measurement is achieved for an electrical waveform. The electrical waveform is sampled and converted to a series of voltages, and the series of voltages is interpolated in order to form a time tag list, using interpolations that are optimized for time interval measurement and analysis. The time tag list accurately represents the times at which particular events of interest occur, and is used to generate displays and results analysis such as adjacent cycle jitter and accurate differential triggering and analysis.
