Intro
A network consist of three resistors connected like a T
Analysis
Formula
Choosing Resistance's Value
R2 = 0
The formula above now becomes
R3 > R1 , Vo > V1 . This network acts as Voltage Amplifier
R3 = R1 , Vo = V1 . This network acts as Voltage Follower
R3 < R1 , Vo < V1 . This network acts as Voltage Attenuator
R3 = 0
The formula above now becomes
This network acts as Voltage Attenuator
R1 = 0
The formula above now becomes
This network acts as Voltage Amplifier 1 +
Summary
This network can be used as Voltage Amplifier, Voltage Follower, Voltage Attenuator by choosing the right value for the resistors
