-Periodically maintenance
This is one of our simulation that we made when we were working on our projects about the physics experiments. Our purpose to make this simulation is may be someday this is could to help students who have not familiar to the Oscilloscope device, especially reading the output voltage, period and frequency. I give random voltage input on it, so our students take exercise to find how much voltage that given to the Osciloscope. This is not our final simulation, your suggestion might be an feedback for our before we give it to our students. Try it!
