Transfer Function

Transfer Functon of a control system is the ratio between the laplace transform of the output signal to the laplace transform of the input signal, given the initial conditions are 0.

Transfer Function =\small \frac{C(s)}{R(s)}=G(s)

Where, C(s) is the output in laplace domain and R(s) is the input in laplace domain. G(s) is used to represent the transfer function.
