一种高效DSO波形显示算法的实现

An Efficient Algorithm of DSO Waveform Display

介绍一种应用于液晶显示的数字存储示波器波形显示的算法。通过分析相邻采样数据之间的大小关系,得到逼近波形的系列直线段;通过分析不同通道直线段的位置关系,得到最佳的线段合成效果;通过分析待清除线段和需绘制线段的位置关系,得到最优的清除和绘图列表。算法可有效地提升示波器的显示速度。

An algorithm of digital storage oscilloscope waveform display used in liquid crystal display is introduced.A series of line which is the best approximation of the waveform can be gained by analyzing the adjacent sampled data.The best unitized result of different line can be gained by analyzing the position of different channel data.The best list of clear and draw can be gained by analyzing the position of line which is needed to be cleared and drawn.This algorithm can improve rate of the display.
