This circuit uses a capacitor with an inverting op amp.

This is the schematic for the op amp and the inverting amplifier. The theoretical output voltage was 2 pi multiplied by the frequency, the resistance, the capacitance, and the amplitude. It then oscillates in a sinusoidal wave. 

This is the graph of the output voltage at 1kHz frequency. You can see that the max is approximately 1.22 V. There is a small amount of excess noise, but the voltage is very consistent.

When the frequency is 2kHz, there appears to be a lot more noise. This has to do with the increase in amplitude and in increase in frequency.

This a very neat graph at 500Hz. It looks very boring and simple and it has a small amount of voltage.

3-31-15: Summing Amplifier

Recall: this is a diagnostic of an op amp. It will simply mirror what is put into it and what comes out as long as it does not exceed the power that is supplied to the op amp.

This is a practice problem to demonstrate the voltage produced by the op amp. Recognizing that there is no voltage on either input and using nodal analysis and KCL.

This is the schematic for a summing amplifier. First we built it using every circuit using a set resistor. Then we built the circuit on a bread board and adjusted the initial voltage while keeping the second voltage steady. We found that the op amp saturated at -3.49 and 4.23. I also found out that my team supports my eating habits and also they like standing waves.

This is the actual Circuit.

Day 10: Inverting Voltage Amplifier

This is the inverting op amp circuit. By changing the voltage in and measure the effects of the op amp. so that the saturation can be seen as well as the voltage that seeps in from the source when the voltage input is zero.

This is the break down of the Op Amp as though it where two seperate components that are just proportionally reliant on each other. The voltage across the resistor and the voltage from the source. Gosh there is so much stuff going on here, It hurts to look at the day before the celebration.

This is the circuit itself using the Op Amp. You can see the source supplied and and the oscilloscope measuring the resistance. I hope there are not any questions about how to use waveform, I would be in trouble. Time to sleep so I have energy to Celebrate tomorrow.!!!!! CELEBRATE GOOD TIMES COME ON!!!!

Day 9: Maximum Power Transfer and Non-Ideal Power Source

This is showing that the resistance that creates the maximum power is when the resistance in the thevenin circuit is equal to that of the thevenin resistance.

This is calculating max power in a circuit.

This is the prelab is used to set up the equations required to calculate the resistance due to the voltage source coming from the analog discovery. it uses a system of equations to measure the adjustment to the system brought on by the voltage source making sure that in one situation it is equal to zero and then changing the resistor.

This is the circuit using the wavefunction to generate a voltage and measure the current. and to measure the resistance inside of the analog discovery.
