How to find transfer function from input and output data?

A transfer function H(f) of a system with input (reference) x and output (response) y is written as the ratio H(f)=Y(f)/X(f), where X(f) is the Fourier transform of x and Y(f) is the Fourier transform of y.

How do you calculate transfer function?

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).

Does transfer function depend on input?

Replacing 's' variable with linear operation. in transfer function of a system, the differential equation of the system can be obtained. The transfer function of a system does not depend on the inputs to the system.

Is transfer function input over output?

Transfer Function. The Transfer function of a system is the relationship of the system's output to its input, represented in the complex Laplace domain.
