Hi OmrP! Welcome to the forums!
Usually, replicating a circuit in Multisim is easiest to do if you have a circuit diagram to work from. The provided image is a good start!
I'd recommend first drawing a circuit diagram by hand from the image you have, and then recreating that in Multisim. If you run into specific trouble when you start building it in Multisim, you can always post back here with those questions.
Best of luck!
