What do you mean by transfer function?
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.
What is transfer function formula?
Concept of Transfer Function
Hence the voltage and current of the circuit can be considered as input and output of the system respectively. From the circuit, we get, Now applying Laplace Transform, we get, The transfer function of the system, G(s) = I(s)/V(s), the ratio of output to input.
Why do we use transfer function?
The transfer function focuses on the steady state response due to a given input, and provides a mapping between inputs and their corresponding outputs. In this section, we will derive the transfer function in terms of the “exponential response” of a linear system.
What is transfer function in Laplace transform?
To find the transfer function, first take the Laplace Transform of the differential equation (with zero initial conditions). Recall that differentiation in the time domain is equivalent to multiplication by "s" in the Laplace domain. The transfer function is then the ratio of output to input and is often called H(s).
