A Transfer Function is the ratio of the output of a system to the input of a system, in the Laplace domain considering its initial conditions and equilibrium point to be zero. This assumption is relaxed for systems observing transience. If we have an input function of X (s), and an output function Y (s), we define the transfer function H (s) to be:dependent change in the input/output transfer function that is defined as the frequency response.
