DIGITAL OSCILLOSCOPE WITH REDUCED JITTER DUE TO SAMPLE UNCERTAINTY

摘要

AbstractJitter due to sample uncertainty in a digi-tal oscilloscope is reduced by horizontally shiftingeach frame of a repetitive waveform display to providean apparent time coincidence of each frame. The timeinterval between a fixed point on the successive wave-forms and the next succeeding clock edge is measured,and a correction voltage is produced to offset thesweep voltage by the corrected amount.
