Abstract

The invention provides a display method of the digital oscillograph. The method includes: reading the sampled data point of present frame; computing the probability which the sampled data point disappears in the same pels point; setting the corresponding relation between the probability and color; the sampled data point displays the corresponding color on the pels point. Also, the invention provides a digital oscillograph. The invention can make user know the disappear probability of every component in signal and disply by the shading color. Even the discrete digital signal, it can make the signal near to nice and smooth.

Description

technical field

[0001] The invention relates to the technical field of digital oscilloscopes, in particular to the technical field of display of digital oscilloscopes, in particular to a digital oscilloscope and a display method thereof. Background technique

[0002] With the rapid development of digital oscilloscope technology in recent years, traditional analog oscilloscopes are gradually unable to meet the needs of the market, but some advantages of analog oscilloscopes are still incomparable to digital oscilloscopes. The display mode of analog oscilloscopes is one of them.

[0003] The analog oscilloscope uses the method of electronically striking the fluorescent screen to display the waveform, and the fluorescent screen has an important feature. When a certain part of the fluorescent screen is struck by electrons more times, the brightness of this part will be higher. Therefore, when the analog oscilloscope displays the waveform, it can not only express the signal conte...
