[paquetabzr]

hi there, i'm new user on multisim, i wanted to simulate a metal detector circuit in multisim 14.0, but i can't complete the simulation, how i'm a new user, could you help me?
I would like to observe the waveform at the entrance and exit of the circuit, for a university work

Hi paquetabzr.

I think you should take some time to watch the tutorial bellow. I believe this can help you to design your simulation since it’s also a Metal Detector Project.

Intermediate Electronics Project #8 - Metal Detector: https://www.youtube.com/watch?v=o6tFlajJBQM

Is this all you need? Could you tell me more about your simulation?

Best regards,
