After following the steps outlined on the following pages, you will have designed a series resonance circuit. Schematic Capture In this section, you will place and wire the components on the workspace shown below. Opening and Saving the File Complete the following step to launch Multisim: 2 1. Select Start»All Programs » National Instruments » Circuit Design Suite 10.1»Multisim 10.1. A blank file opens on the workspace called Circuit1. Complete the following steps to save the file with a new name: 1. Select File » Save As to display a standard Windows Save dialog. 2. Navigate to the location where you wish the file to reside, enter series resonance as the filename, and click the Save button. Placing the Components Complete the following steps to start placing components: 1. Open MyGettingStarted.ms10 as described above. 2. Select Place » Component to display the Select a Component browser, navigate to the AC_POWER as shown below and click OK. The component appears as a “ghost” on the cursor. 3. Move the cursor to the bottom-right of the workspace and left-click to place the component. 5 Virtual Instrumentation In this section, you will simulate the circuit with the virtual oscilloscope. Tip: You can also use Getting Started 2.ms10 from the Getting Started folder (found inside the samples folder). 1. Select Simulate » Instruments » Oscilloscope to place the oscilloscope on the workspace. Wire the instrument as shown below. Tip: To easily differentiate between traces on the oscilloscope, right-click on the wire connected to the scope’s “B” input and select Segment Color from the pop-up. Select a color that differs from the wire connected to the “A” input, for example blue. (Simulation cannot be running when changing wire color or performing any other editing function.) 3. Double-click on the scope’s icon to show the instrument face. Select Simulate » Run. The output of the opamp appears on the scope. 4. Adjust the Timebase to 2mS/Div, Channel A’s Scale to 2V/Div and Channel B’s Scale to 200mV/Div. You will see the following displayed on the scope.

Complete the following steps to perform an AC Analysis at the output of the opamp: 1. Double-click on the wire that is attached to pin 6 of the R1, and change the net name to v_out in the Net dialog box. 2. Select Simulate » Analyses » AC Analysis and click on the Output tab. 3. Highlight V(v_out) in the left column and click Add. V(v_out) moves to the right column. 4. Click Simulate. The results of the analysis appear in the Grapher.
