Which type of amplifier has output voltage equal to the average of all input voltages?
(a) Inverting averaging amplifier
(b) Non-inverting averaging amplifier
(c) Non-inverting summing amplifier
(d) Inverting scaling amplifier
The question was posed to me in an internship interview.
My question is taken from Summing, Scaling & Averaging Amplifier in division Operational Amplifier Applications of Linear Integrated Circuits
