AC Op amps and Oscillators
Today, the class seemed very tired, myself included. I was quite distracted and class seemed really, really long. I had a hard time comprehending a lot of what was happening today.

| Much of this was the same as before. We solved this AC Op amp circuit with nodal analysis, just as we did with DC. |
 |
| We used this equation in order to find the average power of an AC Circuit. |

| The prelab for this lab was to find an R such that we can obtain an angular frequency of 864. This number was the last 3 digits of Andrew's Student ID. In order to do this, we set R_1 and R_2 to the same value, that way Beta becomes 1/2. |
 |
| The circuit we hooked up. We used resistors of 1000Ω. There were no resistors close to 526Ω as we calculated so we used 2 1kΩ in parallel to equal 500Ω. It made the circuit a little messier, but it worked out just fine. |
 |
| After troubleshooting our circuit (I had hooked some components up incorrectly), we were able to obtain this square wave oscillator graph. |
 |
| Finding voltage through the circuit. |
 |
| Finding equivalent impedance through the circuit. |
