- Adjust the signal generator for a sinusoid with a frequency ofabout 1 [kHz] and connect this to the inverting op-amp input.Choose an amplitude so that the amplifier output is about 5[Vpeak]. Observe on the oscilloscope the output of the signalgenerator and the output of the amplifier simultaneously. Sketchthese observations on graph paper, and attach your sketch to theend of this document. Be sure your graph has appropriate axislabeling, as well as units on both axes. Make it readable andneat
-Make measurements of the input signal source vG, the op-ampoutput vOUT, and the voltage at the inverting input of the op-amp,v-. Record these values below. Indicate appropriate units.

-Define polarities for the currents through Rf and Ri in Figure1. Using the voltage values measured in Inverting Op-Amp VoltageMeasurements, calculate values for these currents and record thembelow; again indicate appropriate units. Use measured resistancesfor Rf and Ri, not nominal values.

-Compare the values for the two currents. From this, what wouldyou conclude about the current going into the inverting input ofthe op amp?
-Using your measurements in Inverting Op-Amp VoltageMeasurements, calculate the voltage gain of the amplifier. Recordit here. Calculate the percent error in the actual gain of theamplifier using the ideal gain as a reference. Av = % error=
-Estimate the maximum percent error you would expect to havemade in your measurements, assuming the oscilloscopes arecalibrated to within 1%. Remember your resistance tolerance. Wereyour measurements in agreement with theory? Comment. Maximummeasurement error (estimated)
