Homework Statement
There are unknown values for input voltage, but we know it is sinusoidal. There is an inverting amp connected in parallel with a non inverting amp. The goal is to find the output voltage.
I have three questions.
1: if the problem states that "power rails for both opamps are in the same range" what does that mean, what is a power rail?
2: Is it safe to assume Vin to each amp are equivalent bc the voltage would be the same through the separate parallel branches.
3: Should the output voltage of each opamp add to the total voltage, or should they be equivalent to each other (and the total) because it is all the same loop?
Homework Equations
Inverting amp: vout/vin = -r2/r1
non inverting amp: vout/vin = 1+(r2/r1)

The Attempt at a Solution
I do not need/want help with a full solution. Simply a few questions about summing amplifier voltages.
