Summing Amplifier

Operational amplifiers can be used for simulating mathematical operations like addition, integration, differentiation etc.

Objective

Make a summing amplifier using an Op-Amp and test it.

Procedure

The output is given by V_{o}= \frac{R1}{Rf}V1 + \frac{R2}{Rf}V2 + ...

Discussion The summation can be done using AC waveforms also. Our supply voltage is only 6V. So the output should be kept less than 4V.
