Quick Start
The schematic is wired as shown in the diagram below. Ri = 1k and Rf = 10k. The WG amplitude is set to 80 mV, you may try a 1 volt input to observe the clipping of the the output, since it exceeds the supply voltage of +/- 6 volts.
Screenshot of the UI
Screen shot of the oscilloscope program showing inputs and output of a Non-Inverting Amplifier. Theoretical Gain is -11.
Exercises
- Calculate the gain by fitting A1, and A2 by enabling the check-boxes next to them. gain = output/input
- What is the gain if Rf < Ri .
Write Python Code
This experiment can also be done by running this Python Code.
