Lab Day 11

Summing Amplifier Lab

In this lab assignment, we implemented a simple operational amplifier-based circuit. Since operational amplifiers are used commonly in circuits used to implement mathematical operations, we implement the processes of summing two voltages.

On the left side there is a schematic of the circuit with the measure resistance values. Below there is the equation used to find output voltage. On the right side there is a table showing Va with the measured and calculated values of output voltage and the percent error.

This is a picture of the circuit.

Difference Amplifier Lab

In this lab assignment, we implemented a simple operational amplifier-based circuit. Since operational amplifiers are used commonly in circuits used to implement mathematical operations, we implement the processes of taking the difference between two voltages.

On the left side there is a schematic of the circuit with the measure resistance values. Below there is the equation used to find output voltage. On the right side there is a table showing Va with the measured and calculated values of output voltage and the percent error.
