When increasing the voltage from 21V to 36V and connecting a 50-ohm load, it is found that the power must be turned on first and then the load is connected. If the load is connected and then powered, ...
I wrote a simple serial port program using AT89S52. After writing the program into the chip, it can receive data normally. However, when the AT89S52 is powered off and then powered on, it cannot recei...
In ordinary low-frequency digital-analog mixed circuit applications, the most likely interference is common-channel coupling interference, not crosstalk. The following is an example of a design applic...
