1. Provide the relationship between the input and output voltages that you determined in the pre-lab. Why is the circuit is called a difference amplifier?
2. Provide a schematic of the circuit you implemented, including actual resistance values used in your circuit.
The actual value of resistance we used in this lab is:
R1 = 9.94K, R2 = 19.9K, R3 = 9.98K, R4 = 19.7K
3.Attach a table of output and input voltages for your circuit. Also attach a plot of the output vs. input voltages.
4.Provide a brief discussion of your results and a comparison between measured and expected circuit response. Include any observations you made relative to saturation of the output.
According to our experimental data, the equation
matched our experimental data which means that this equation is true. However, the maximum and minimum output voltage cannot reach 5V because of saturaty.
Summary
The same as summing amplifier because we learned them in the same day.
