The Research on Waveform Parameter Automatic Measurement Algorithm of Digital Oscilloscope
Abstract: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.
