1) check with a multimeter power block is good or bad electrolytic capacitor electrolytic capacitor of the two leads are positive and 41 datasheet and negative points, its good or bad in check, the electrolytic capacitor for low voltage (6V or 10V), power block should be placed on R 100 block or R lk block, the red pen then the capacitors negative turbulent, black pen then the positive side, then meter pointer will swing, and 41 price and then back to zero or near zero. This electrolytic capacitor is good. The greater the capacity of electrolytic capacitor, the longer the charge, was also slower swing pointers. 2) electrolytic capacitor with a multimeter to determine the positive and 41 suppliers and negative lead some of the low voltage electrolytic capacitor, if the positive and negative lead marked unclear, according to the ...

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 th...
