System for real-time display of the waveshape of an incoming stream of digital data samples

摘要

The data flow rate of a first series of sample values generated over time is reduced to a rate acceptable for real time plotting by generating a second series of sample values where each sample in the second series is representative of a plurality of samples in the first series. The times of the representative values are representative of the times of nonplotted values. Plotting density is increased by plotting only representative values and/or representative time points.
