Hi Seabar,


My name is Jaimie, I'm an applications engineer at National Instruments.


I am unsure what it is you're asking here?

Are you having trouble finding these components within multisim and therefore cannot implement the given example circuit? 


Please correct me if I have interpreted the question incorrectly.

As you're not able to find the components that you're looking for in multisim , I would suggest using the component Wizard, this allows you to create your own component. I have included a link to a site that gives a step-by-step guide on how to do this.

I hope this is useful to you, let me know if you have any further questions.
