Didn't they say that they have it since 2007? How come the latest version 9.5 doesn't have it? The network label is only displayed in the lower left corner, not on the line. Don't say it's a color pro...
I just started to use power modules and want to make a 12V/25W power supply to power the amplifier. The initial plan is to pass 220V AC through a 24V/30W transformer, then through a bridge stack and t...
If the field effect transistor is connected as shown in the figure, is its function equivalent to that of a diode? If so, what is the main difference between it and a diode?...
Finally I have time to sort out the FPGA books I have received. I will read them first to see if the content is valuable. Some free resources can be found in my downloads. As for the others, I believe...

Although it is relatively easy to check the stability of a simple amplifier at lower frequencies, it may be much more difficult to evaluate the stability of a more complex circuit. This artic...[Details]
From the PIC16F946 datasheet, we know that there are two ways to write values to the LCD for display:
1. Directly write the value to LCDDATA1~LCDDATA23
2. Use disconnect t...[Details]
Xiaomi, a well-known Internet phone in mainland China, won a million-unit order contract from China Unicom on November 20 last year, which made Xiaomi famous in mainland China. In April this year...[Details]
With concerns about the growing energy crisis, motor efficiency has become an important and timely topic. This is because motors use 63% to 70% of the electricity produced in the United States and ...[Details]
