If the gain of a non-inverting averaging amplifier is one, determine the input voltages if the output voltage, if the output voltage is 3v?
(a) V1 =6v ,V2=3v and V3=2v
(b) V1 =9v ,V2=5v and V3=-4v
(c) V1 =8v ,V2=-6v and V3=1v
(d) V1 =7v ,V2=4v and V3=-3v
I was questioned about this in a national level competition.
The above asked question is from Summing, Scaling & Averaging Amplifier area in topic Operational Amplifier Applications of Linear Integrated Circuits
