Create an Input Signal
In this step of the Quick Start Tutorial we will create an Input Signal that will be used on the next page as an input to the Vin Voltage source of the example circuit shown here:
Creating an Input Signal
- Select Input Signal
from the Components Toolbar.
- To insert a new Input Signal into the circuit document, click the left mouse button,
drag until you see a rectangle (the Input Signal will use the entire area of the rectangle), and then release. The Signal Designer dialog box will appear.
This dialog box can be used to design almost any input signal. For this example we will create a simple step function.
- Enter "Step" into the edit field in the upper left corner of this dialog. This gives the signal a label (a name) so that we can refer to it later when we assign a signal to the Voltage Source Vin.
- The Start and End values are specified in seconds. Leave the Start value at 0 and set the End value to 1.
- Now click the Add Compound Element button. The Compound Signal Element dialog box will appear:
Set the Start value in this dialog to 0.25 and set the K value to 1. Then click the OK button.
- The Signal Designer dialog box should now look like this:
Click the OK button.
- The new Input Signal, "Step", will appear in the circuit document like this:
If you have trouble completing the steps in this page of the Quick Start Tutorial, you can load the file QuickStart4.crc from the Tutorials\QuickStart directory. This file contains a circuit document that contains all the elements created so far in this tutorial.
