  • Pre-interpolation adaptive filter
    Patent number: 4789950
    Abstract: An adaptive filtering procedure reduces overshoot which may be present on a waveform having infinite slopes displayed on a digital oscilloscope as a result of interpolation between samples at the location of the infinite slopes. An adaptive filtering procedure identifies sampled points adjacent the infinite slope and moves the points closer to each other to avoid ringing or overshoot on the display. Before modification, a straightness test relative to the waveform before and after a discontinuity and a test for sudden changes in the waveform before and after the discontinuity are performed.
