Furthermore, the users can acquire real data off of their myDAQ devices and compare it to their simulated ones. The template allows you to draw wires connecting your captured schematic with the lines on the virtual myDAQ device, the same way you would connect your breadboard circuit to the actual myDAQ device.Īlso, Multisim integrates NI Elvismx instrumentation within this template, allowing the users to simulate their schematic capture using familiar interfaces. These will represent the actual panels or slots that are available on myDAQ. The template, once open, will have two connecting slots: the myDAQ right slot and the myDAQ bottom terminals. (Multisim needs to be installed prior to the installation of the DAQmx software) Troubleshooting: If you can’t find the template, reinstall DAQmx. This can be found in Multisim main toolbar at File>New>NI myDAQ Designįigure 1: Launching the NI myDAQ Design Template You can access myDAQ instrumentation in Multisim by opening the “NI myDAQ Design” template.
The exercises also require the use of a breadboard, a capacitor (.1uF), a resistor (1kohm), and wires. The user should have all the components installed in this specific order: LabVIEW, Circuit Design Suite, DAQmx. Also, this document requires the installation of the myDAQ Software Suite. Should I now expand the Thévenin expression, first it's likely that I make mistakes while expanding the equations but, second, I will need more time to format the expression in a nice low-entropy format.To replicate the exercises in this document, the user needs to have myDAQ plugged in. If I count the time needed to determine the expression using FACTs, it does not exceed a few minutes. As shown in the below plots, all three expressions deliver the exact same response: As I said, should you spot a small deviation, then review the individual sketches and fix the guilty one without restarting from scratch as any other analysis would require:īecause the roots are real in this circuit (the quality factor is low), you can try to model the transfer function with two cascaded poles and a zero. I usually build a high-entropy expression obtained with Thévenin in this case and make sure both answers are rigorously similar in magnitude and phase.
This is it, we have everything to be happy and a Mathcad sheet can check these results. The methods relies on determining the time constants when the stimulus - \$V_\$. However, and it could be the issue for an exam, I am not sure if the person who reviews your contribution will recognize it as a valid method as he/she perhaps expects the classical KVL/KCL approach. If you want to be fast and be efficient to determine transfer functions, there is no other way than resorting to the fast analytical circuits techniques or FACTs that I describe in my book on the subject.
