Summing Amplifier
In this lab, we calculate the three resistors and set up a Summing Amplifier Circuit in order to record the amount of Vout. This output voltage will be measured by adjusting Va.
From the picture below, we calculated that the three resistors will have the same resistance of 2.2KΩ.
Then after measuring the three resistors, we got the actual amount of resistance and then we set up the circuit as shown below:
Once the circuit is set up, we then adjust the Va voltage to find the output voltage. As shown below, Vb is a constant 1:
