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 models the system's output for each possible input. It is … See more

If $${\displaystyle x(t)}$$ is the input to a general linear time-invariant system, and $${\displaystyle y(t)}$$ is the output, and the bilateral Laplace transform of $${\displaystyle x(t)}$$ and $${\displaystyle y(t)}$$ is See more

In imaging, transfer functions are used to describe the relationship between the scene light, the image signal and the displayed light. See more

Transfer functions are commonly used in the analysis of systems such as single-input single-output filters in signal processing, communication theory, and control theory. The term is often used exclusively to refer to linear time-invariant (LTI) systems. Most … See more

In control engineering and control theory, the transfer function is derived with the Laplace transform. The transfer function was the primary tool used in classical control engineering. A See more

Transfer functions do not exist for many non-linear systems, such as relaxation oscillators; however, describing functions can sometimes be … See more
