[align=left]When I used the resistor voltage divider and INA128 differential amplifier method to detect AC 220V voltage, a strange phenomenon occurred: when AGND was connected to the ground wire of th...
The microcontroller is powered by 5V, and the voltage ripple from the 7805 input and output after filtering is about 50mVpp. Electrolytic capacitors and 104 capacitors are added for filtering before t...
I would like to ask if anyone has used this NMOS tube, if the GS input voltage is 3.3V, what is the DS output current? The datasheet does not specify...
We may know some self-help methods in emergency situations, but you may not know that your mobile phone can also save your life in a critical moment. Check out the following content to learn what your...
Implementing DSP with hardware is basically based on fixed-point algorithms. What is fixed-point? Fixed-point means that the position of the decimal point is fixed, which is different from floating-po...
