The Transfer Function of the Non-Inverting Summing Amplifier with “N” Input Signals
Sunday, August 9th, 2009Summary:
In a previous article, How to Derive the Summing Amplifier Transfer Function, I deduced the formula for the non-inverting summing amplifier with two signals in its input. But what if we have 3, 4 or an n number of signals? Can we add them all with one amplifier?
