This was some want something I was able to do. It took  me a while to get back into my mojo. OH... here is Q and B. I did not know what that meant  on the final. Lab In the pre-lab we needed to figure out how the circuit would  respond in many different frequencies. In the end we got good data and everything was the way it was suppose to be. It took a long time to just get the numbers. it felt like busy work.

First day back from being sick and I am totally lost. I was really CONFUSED at this point.

Today was my sick day. Was at school to snap this one picture but I throw-up and then left.

Lab Conclusion

Just a simple day of calculating angles. The first two pictures are basically the same thing. They just show simple phases angles being calculated. This last picture is how we will for now on calculate the angle and radius of a given phaser.  It was a very simple day.

Looking back to this day in lab made me wonder how it looked so hard before. We just had to follow some simple steps to find "a" and "w" . Then find s1 and s2 for the circuit This was a different problem but here we determined if the circuit was over damping, under damped or critically damped F ollowing that we found the ratio of a/w. LRC Lab I n the pre-lab we had to theoretically find how the circuit would react to the given conditions  I t was a simple circuit as seen about. We has to measure the response across the Cap and Inductor.  Conclusion  In the end the circuit acted the way that we thought I would in the pre-lab. The graph below shows the discharge of the capacitor (I think).

Some re-hashing of what we did a week ago. We got our predictions wrong because there was a negative in the equation. Lab For some reason we did not get a picture of our pre-lab were we determined that 234Hz would be the best possible frequency for the lab. Here is the op amp with 234hz sin wave going into it. As you can see it is a perfect gain of one starting from -A since the equations showed that it would happen like that. The rest of the graphs are the same but at 500hz, 1kHz, and 2kHz

Don't know how to rotate the picture but this was just the pre-lab. We learned that it takes 5 delta to charge up a capacitor. Lab This lab was just us charging and discharging capacitors. Not much calculation was being use but we did learn how to trigger in waveform Discharging capacitor Same discharging capacitor but shifted Charging capacitor Charge/Discharge capacitor Summary It is what it is. What new is there to be said.

Move Time! Have you ever wanted to blow something up. Well you can't but above there is a capacitor exploding if the video works. This is how the solve the problem of charging a capacitor too fast. They add a resistor. A inductor would work better but why spend the money. When adding capacitors you add them like opposite of resistors. Taking the integral of graphs that represents the voltages going through an amp.  The following graphs are what we did on the white board but on the waveform. This was an induced wave at 1k Hz Same as the previous one but at 2k Hz Summary Each of the graphs acted the way that we thought we would. Some of the graphs as a flat peak witch means that we were most likely saturating the capacitor. Besides that the we nailed this one.
