Abstract
Jitter due to sample uncertainty in a digital oscilloscope is reduced by horizontally shifting each frame of a repetitive waveform display to provide an apparent time coincidence of each frame. The time interval between a fixed point on the successive waveforms and the next succeeding clock edge is measured, and a correction voltage is produced to offset the sweep voltage by the corrected amount.
