Abstract
Waveform digitization techniques and apparatus are shown. An input waveform is shown on a display device such as an oscilloscope as a high density sequence of either horizontal or vertical line segments which track the overall shape of the waveform. This digitization technique includes determining minimum and maximum values of the input waveform and storing these as sets. As these minimum and maximum samples are collected, each sample is compared with a previous minimum and maximum value that had been found during a current line period. The minimum and maximum values for the total line period are stored in a memory. Under processor control these sets of minimum and maximum samples are displayed on a visual display device such as an oscilloscope.
