Step Response of a Feedback System

In this example we will show the performance of a feedback system using only ABM parts. Wire the circuit below  

We would like to see how the output step response changes for different feedback gains. Presently the feedback gain is 1E3 or 1000. We would like to vary the feedback gain to see how the feedback affects the operation of the system. We will use a parameter to change the value of the feedback gain. Double-click on the text PARAMETERS to obtain the parts spreadsheet  

Click the New Column button to create a new parameter and fill in the dialog box as shown  

Select the FBjJOln column and then click the Display button
