Therefore, output voltage Vo = -{[(RF/Ra) Va] +[(RF/Rb) Vb]+[(RF/Rc) Vc]}. 6. An amplifier in which the output voltage is equal to average of input voltage?
A. Summing amplifier
B. Weighting amplifier
C. Scaling amplifier
D. Averaging amplifier
Answer:A
Therefore, output voltage Vo = -{[(RF/Ra) Va] +[(RF/Rb) Vb]+[(RF/Rc) Vc]}. 6. An amplifier in which the output voltage is equal to average of input voltage?
A. Summing amplifier B. Weighting amplifier C. Scaling amplifier D. Averaging amplifier
Explanation: An averaging amplifier can be used as an averaging circuit, in which the output voltage is equal to the average of all the input voltages. 7. Find out the gain value by which each input of the averaging amplifier is amplified ?( Assume there are four inputs)
