 Start by shutting off the power supplies and assemble the circuit. As with the summing amplifier circuit earlier, use the second waveform generator output for the DC source Vref , and turn the amplitude to zero and the output offset all the way down so that you can adjust up from zero during the experiment. Start by shutting off the power supplies and assemble the circuit.

-Again configure the waveform generator Vin for a 2V amplitude sine wave at 1 kHz. With the power supply on and Vref at zero volts, export the output waveform.+Again configure the waveform generator Vin for a 2V amplitude ​peak-to-peak ​sine wave at 1 kHz. With the power supply on and Vref at zero volts, export the output waveform.
  
 Now slowly increase Vref and observe what happens. Record the output waveform for Vref = 1V. Keep increasing Vref until it exceeds 2V and observe what happens. Can you explain this? Now slowly increase Vref and observe what happens. Record the output waveform for Vref = 1V. Keep increasing Vref until it exceeds 2V and observe what happens.
