数字示波器中波形参数自动测量算法研究

The Research on Waveform Parameter Automatic Measurement Algorithm of Digital Oscilloscope

在数字示波器中为了能自动测量波形参数,既方便读数,又提高测量精度,本文通过对幅度类参数和时间类参数的分析,利用众数直方图和窗口比较法,找出峰峰值、周期、上下升沿时间等自动测量参数的算法,并在Qt/designer中运行,测量结果表明高精度的完成了参数自动测量。

In the digital oscilloscope in order to automatically measure the waveform parameters,both for the convenience of reading,but also improve the measurement accuracy,the paper type parameters of amplitude and time parameters of class,using the plural histogram and window comparison,find the peak to peak,cycle,rise up and down along the time of the algorithm automatically measured parameters,and the Qt/designer to run,the measurement results show that the completion of high-precision automatic measurement parameters.
