LR 1 From part one we found that the v o1 value was 2.5 volts. So then we applied that voltage to the circuit that was drawn out on Figure 6.1(b). Then we measured v 02 with the multimeter and the value was 1.251. There was no error in our values compared to the accepted values that we calculated which was also 1.251. LR 2 When you combine the two stages I thought that you should get the same output. When we did it we got a value of .84 ± 0.001 Volts, which is not the same as 1.25. The reason for this voltage drop was because of the loading effect. The loading effect was caused by the fact that the two circuits where not isolated from each other. Since the input impedance was too low on the first stage it resulted in the circuit acting differently that expected. LR 3 In this part of the lab we are told to make a voltage follower using an op amp and a similar set up as to the week before. The voltage follower takes the voltage that you

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
