I installed vmtools in the virtual machine, added a shared folder in the virtual machine settings, and ran vmware-config-tools.pl in the virtual machine Linux, but the folder I set still doesn't seem ...
As the title says, I have been using BAV99 for a long time but still don't understand how to use it. I checked online and found that it is TVS, but it has 3 pins. How to connect them specifically? The...
Is there any IC that can realize the function of key volume control? Under the premise of not requiring system software control, use key control to adjust the volume, not mechanical control like volum...
A while ago, I bought a second-hand Tonghui TH2817A 100K precision LCR digital bridge out of boredom. This is a classic LCR digital bridge product with a good reputation from Tonghui. It has an accura...
Analog engineers have traditionally struggled with complexity when designing power supplies that required multiple outputs, dynamic load sharing, hot-swap, or extensive fault-handling capabilities....[Details]
The reason for the light decay of white LEDs: the decline of phosphor performance
So far, the rapid decline of the luminous performance of white light LEDs, especially low-power white light LE...[Details]

Lijia'an Yellow River Diversion Culvert is a large gravity diversion gate in the lower reaches of the Yellow River. The Yellow River Diversion Culvert is located in Lijia'an Vi...[Details]
Abstract: Based on the analysis of the characteristics of the IRIG-B (DC) code type, a design method for IRIG-B (DC) time code decoding is proposed. This method consists of a small number of periph...[Details]
Traditional synthesis techniques are increasingly unable to meet the needs of today's very large and complex FPGA designs implemented in 90nm and below process nodes. The problem is that traditio...[Details]
Some people think: as long as the program runs well, it doesn't matter how the original program is written. But this is absolutely not the case. Software is not completed in one go, and it is neces...[Details]
The circuit has overcharge protection, over-discharge protection, over-current protection and short-circuit protection functions. Its working principle is analyzed as follows:
