Properties of Transfer Function

1.	Properties of Transfer Function
Answer» • The transfer function of a system is the mathematical model expressing the differential equation that relates the output to input of the system. • The transfer function is the property of a system independent of magnitude and the nature of the input. • The transfer function includes the transfer functions of the individual elements. But at the same time, it does not provide any information regarding physical structure of the system. • The transfer functions of many physically different systems shall be identical. • If the transfer function of the system is known, the output response can be studied for various types of inputs to understand the nature of the system. • If the transfer function is unknown, it may be found out experimentally by applying known inputs to the device and studying the output of the system.
