Dr. Abner Mallity needs an amplifier with a gain of 10. He does not care if the amplifier changes the sign of the signal. However, he has been having trouble with the circuit and has enlisted your help. The circuit he wants to use is shown below.
The values he chose were:
R1 = 500W.According to his calculations this gives a gain of -10. He hasn't had time to check the circuit, however. He wants you to do the following. He's trying to develop an op-amp experiment for his students, and part of what he is doing is to check out his set of instructions to them.
R0 = 5000W.
1. He set up a function generator to provide a sine wave at 1000 Hz. (And because he is extremely persnickety about the quality of the waveshape, he insists on using the HP function generators, and won't countenance the sound card function generator for this, so use the small HP function generators for this experiment.)
2. Using an oscilloscope, carefully set the sine wave output of the function generator to have an amplitude of 0.50v (1.0v peak-to-peak).
3. Connect the function generator to the op-amp inverter circuit
4. He calculates that with a gain of -10, he should get an output signal that is 5v amplitude (10v peak-to-peak).
5. Measure the output of the operational amplifier.
6. Write up and evaluate and explain your results.
