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.

Day 8: Thevenin's Theorem

This circuit is simplified to measure the one resistance and the one voltage so that as you change one resistance it is easier to calculate its effects on the system.

This is all the work, measuring all the components so that theoretical and experimental can be seen simultaneously. The thevenin resistance and thevenin voltage effects as one resistor is changed and how the voltage across it will change accordingly.

This is everycircuit, it should the current and voltage throughout a theoretical circuit. 

This is the circuit that is used for the experiment using a potentiometer to change the resistance.

This is the thevenin circuit.
