The method to identify the three poles of thyristor is very simple. According to the principle of PN junction, you only need to use a multimeter to measure the resistance between the three poles.The f...
I would like to ask all the heroes!! I can now use RAS to dial up the Internet. I would like to ask how to know whether the dial-up is successful? Which function is called? There is another question!!...
This is a CPLD learning board I DIYThe purpose of DIY is to learn and understand the development process of CPLD, so the function is relatively simple, with only a few LEDs, hahaSince it is all handma...
When the voltage waveform at the AD port of DSP is a pure sine wave (as shown in the red waveform), the AD sampling result will have non-periodic bad pixels (as shown in the blue waveform). The figure...
It is required to be powered by a 3.6V battery, which needs to be converted to 3.3V (more than 400mA) and 1.8V (100mA is enough). In order to squeeze out as much power as possible, I hope it can still...
Voltage Reference and Time Reference All analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) require a reference signal, usually a voltage reference. The digital output of an A...
