Abstract
A method of determining an intensity value for a pixel in a display for displaying digitized waveforms. The intensity values simulate an analog display so that intensity at high slew rates about a point is lower than intensity at low slew rates about a point. Intensity may be computed as a function of slew rate. Alternatively, for speed, the absolute difference between waveform magnitudes at consecutive samples is used as an index into a pre-computed table of intensity values. As a result, for each sample, only a subtraction and a table look-up are needed to provide intensity variation. In an alternative embodiment, intensity values are higher at higher slew rates to accentuate rising and falling edges of digital waveforms.
