1/7Introduction to Multisim: Learn to Capture and Simulate in Less Than 30 Minutes1. 2. 3. 4. 5. 6. 7. 1. 2. OverviewNI Multisim is an easy-to-use schematic capture and simulation environment that engineers, students, and professors can use to define and simulate circuits. This article shows you how to captureand simulate a simple circuit in Multisim. This tutorial takes less than 30 minutes to complete and consists of 50 short steps. The example circuit in the article is an amplifier circuit. This noninverting operational amplifier configuration consists of one active component (the operational amplifier) and two passive resistorcomponents that will be used to complete the feedback network to provide gain in this circuit.
