I was recently adjusting the PWM wave and found that when the frequency of the PWM wave is very high (such as 200KHz), the output PWM waveform is normal, but when the frequency is reduced, such as to ...
I am not good at hardware, and I would like to ask some common AD conversion questions: 1: In the picture, what is the difference between the negative power supply of the AD chip being grounded and co...
Because when simulating in protues, the power supply and grounding parts are hidden, I don’t know how to connect the isolated power module, how to design a power isolation module......
