| Feb 17, 2013 at 2:17 | comment | added | Matt Young | The signals are being amplified or attenuated individually and summed. As bitrex said his comment, the gain in the summing amplifier can only be quantified with respect to a single signal. Trying to do the same for the entire system yields a meaningless result. | |
| Feb 17, 2013 at 2:07 | comment | added | Richard | Is there such a thing as total gain? If so, is it \$ A_{total}= -\frac{R_3}{R_1} - \frac{R_3}{R_2} \$? | |
