Summing Amplifier Practice
Practice question for ECE201: "Linear circuit analysis I"
By: Chinar Dhamija
Topic: Summing Op Amp
Question
Find the output voltage, Vout.
Answer
First we know that $ V_- $ = $ V_+ $
$ V_- $ = 0V = $ V_+ $
The op amp can be ignored for this particular problem.
We can apply the formula we learned in class to solve for Vout.
$ \begin{align} Vout = (\frac{\frac{-R_f}{R_1}})V_1 + (\frac{\frac{-R_f}{R_1}})V_2 Vout = -24V \end{align} $
