Question
An averaging amplifier has five inputs. The ratio Rf>Rin must bea.0.2b.5c.1d.none of these
Solution
The averaging amplifier is a special type of operational amplifier where the output voltage is the average of the input voltages. It is used when you need to amplify the average of several signals.
The ratio Rf/Rin in an averaging amplifier is determined by the number of inputs. In this case, the amplifier has five inputs.
The formula for the ratio Rf/Rin in an averaging amplifier is 1/n, where n is the number of inputs.
So, for an averaging amplifier with five inputs, the ratio Rf/Rin would be 1/5 = 0.2.
Therefore, the correct answer is a. 0.2.
