What is the transfer function of a system?
In engineering, a transfer function (also known as system function or network function) of a system, sub-system, or component is a mathematical function that theoretically models the system's output for each possible input. They are widely used in electronics and control systems.
How do you identify a transfer function?
Finding the transfer function of a systems basically means to apply the Laplace transform to the set of differential equations defining the system and to solve the algebraic equation for Y(s)/U(s).
