The cameras I have are all like this. When the light is a little dim, the frame rate drops to about 12, and there is also ghosting, which is quite annoying. I would like to know why this happens. Coul
Hello everyone, I want to ask how to use PWM wave to control the power of the heating wire. The period of PWM wave is about 33ms. Is it better to use thyristor or solid state relay? Will too frequent
Circuit diagram:Input voltage: 7.4V, output 6V, 1A. The output waveform measured by oscilloscope is as follows:With such a large interference, the power supply is completely unusable. Please help me f
