Calculate the output voltage due to the summing amplifier shown in Fig. 5.75.

Step-by-step

{v}_{{o}} =-[\frac{{R}_{{f}}}{{R}_{1}} {v}_{1}+\frac{{R}_{{f}}}{{R}_{2}} {v}_{2}+\frac{{R}_{{f}}}{{R}_{3}} {v}_{3}+\frac{{R}_{{f}}}{{R}_{4}} {v}_{4}] =-\left[\frac{50}{25}(10)+\frac{50}{20}(-20)+\frac{50}{10}(50)+\frac{50}{50}(-100)\right] \\ =\underline{-120 \mathrm{mV}}
