I built a standard voltage-controlled voltage source second-order low-pass filter circuit (cut-off frequency 2k) using LM358P, but after testing it with a frequency sweeper, I found that the amplitude...
In the previous experiment, we made a light flash off, on, off, on. Then, if we turn on the second light instead of the first light after the first light goes out, and then turn on the third light aft...
I have been working for almost two years, and I have been working on microcontrollers, but I mainly write programs (in C). There are people who specialize in hardware circuits. Hardware is my weak poi...
