Question
For the circuit shown in Figure P9.28, show that if $R_1 / R_2=R_3 / R_4$, then $v_o=\left(R_2 / R_1\right)\left(v_1-v_2\right)$, assuming an ideal op amp.Figure P9.28 can't copy
Step 1
Since we are assuming an ideal op-amp, we know that the voltage at the inverting terminal (V-) is equal to the voltage at the non-inverting terminal (V+). Show more…

Show that the output of the circuit in Fig. P4.28 is \[ V_{o}=\left[1+\frac{R_{2}}{R_{1}}\right] V_{1}-\frac{R_{2}}{R_{1}} V_{2} \]
Find $V_{o}$ in the circuit in Fig. $\mathrm{P} 4.22,$ assuming that the op-amp is ideal.
Show that the output voltage $v_{o}$ of the circuit in Fig. 5.67 is $$v_{o}=\frac{\left(R_{3}+R_{4}\right)}{R_{3}\left(R_{1}+R_{2}\right)}\left(R_{2} v_{1}+R_{1} v_{2}\right)$$
