| Aug 29, 2015 at 15:24 | comment | added | Bruce | My answer is specific about differential amplifiers: "The Difference is (S+noise) - (-S+noise) = S+S+noise-noise = 2S" This is specific on the input of the differential amplifier | |
| Aug 29, 2015 at 15:18 | comment | added | JGalt | Thank you! But my question was specific to differential amplifiers. Both inputs to the differential amplifier need not be equal and opposite. What would be the meaning of common mode voltage in such case? | |
