Teaching Analog / Digital Circuits Lab
Circuit simulation and measurement are fundamental to an understanding of passive and active circuits. we use tools from the National Instruments circuits teaching platform to these concepts in a interactive manner. With the NI ELVIS modular engineering education platform combined with LabVIEW and Multisim software, we can able teach circuit concepts in Basic Circuits Lab, Analog and Digital Circuits Lab etc.,
By using this technology, the students acquire a thorough knowledge of passive and active circuits and the instrumentation used to evaluate their performance. With the flexibility and power of NI ELVIS, LabVIEW, and Multisim, students can simulate circuits before the lab and perform automated measurements to gain a deeper understanding of how circuits behave and the factors that affect it.

Simplifying Circuits Education for Students
 
Students complete homework assignments by simulating circuits with Multisim and evaluating real-world circuit performance and characteristics using NI ELVIS and LabVIEW. Multisim is used to set limits on the possible performance of circuits while NI ELVIS, LabVIEW, and LabVIEW Signal Express provide an understanding of the performance that can be obtained with actual physical components.
With its specific pedagogical features such as 3D NI ELVIS, interactive quizzes, and advanced analysis features, Multisim is an ideal tool for teaching circuit theory. NI ELVIS, with its 12 integrated instruments and compatibility with Multisim and LabVIEW, helps students build and measure the simulated circuits on a standard PC running the Windows operating system. Together, NI ELVIS, Multisim, and LabVIEW, reduce the time required for the teaching and laboratory process.
This combination of NI software and hardware for laboratory use has proven effective for reinforcing theoretical circuit concepts. Our students also respond favourably to using these tools. We believe that this equipment was a wise investment for the Georgia Tech School of Electrical and Computer Engineering and hope that we can continue to use this platform more in future classes.
