41. Oscilloscope glitch causes that? How to eliminate?

We know that the signal through the device logical unit connection, there must be delay. The size and 41 datasheet and the connection delay is not only the length and 41 price and the number of logic cells, but also to have and 41 suppliers and device manufacturing process, the working environment and so on. Therefore, the signal transmission device, the time required can not be accurately estimated, when multiple signals simultaneously the moment of transition, we have a "competition and adventure." At this time, often there will be some incorrect spikes, these spikes is a "glitch." If the glitch is inherent in the signal, and you want to sync with the edge of the trigger signal (eg sine wave), can trigger high-frequency suppression means, usually synchronized to the signal. If the signal itself has a glitch, but want to filter out the glitches oscilloscope does not display glitches, often difficult to achieve. You can try to use the method of bandwidth restrictions, but accidentally filter out the signal itself may also be part of the information. If you use logic analyzers, in general, the use of state acquisition approach, some collected in time mode glitches on to see it.
