V. Inverting Integrator For this part, we were given a circuit (Fig. 13) to build. We then measured the input and output functions with the oscilloscope. The properties of the input voltage were a square wave with a 1V peak-to-peak amplitude and 100Hz frequency. Figure 13. The inverting integrator circuit

Input Output Wave Type Triangle wave Square wave () 0.960 2.94 Frequency () 98.62 98.66 With these results, we can measure the voltage gain and the phase shift: Conclusion All things considered, this lab could have gone much smoother. Building the circuits using solely a breadboard proved to be time-consuming, but was not very difficult. In the same vein, using the oscilloscope to properly measure things for the first time was also new, and as such it took a large amount of time to get just right. However, we managed to illustrate the concepts presented and gain a deeper understanding of the operational amplifier and its uses.

Error, as always, was an omnipresent complication, yet to an even greater degree in this experiment. Each circuit built proved to have some fickleness that would offset the data in horrendous ways, such as our ground being moved from one position to another, getting too close to the oscilloscope probes, or any other slight deviation from perfection. That having been said, we were able to get the work done, and analyze the circuits. All in all, this lab was incredibly informative, outstanding in its oscilloscope observations of op-amps, though thoroughly time consuming.

    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.
