I need to perform
Vout= 0.5 V1 + 0.6 V2 + 0.9V3 - 0.8 V4 -0.9 V5
I know that I have to use superposition.I can easily solve those negative terms simply by assuming Rf and then finding out R1,.. to be connected to the negative terminal of op-amp. But for finding out the positive terms I have many equations and I think I have to solve three equations which has three unknowns and hence it has a unique solution which means that I can't assume a value for any of the resistors.I think it will be very cumbersome. Is there any other easy method?
Thanks in advance.:-D:-D
