4.1. Connect the circuit on the breadboard and show it to your TA.
4.2. Observe and draw waveforms at pin 2 (input) and pin 6 (output) of the op-amp in Figure
6.14 of the Lab Measurement Sheets.
4.3. Explain how this circuit operates. What is the range of output signal change when you
change the potentiometer position and its resistance?
