A transfer function is a convenient way to represent a linear, time-invariant system in terms of its input-output relationship. It is obtained by applying a Laplace transform to the differential equations describing system dynamics, assuming zero initial conditions. In the absence of these equations, a transfer function can also be estimated ...A SISO continuous-time transfer function is expressed as the ratio: G (s) = N (s) D (s), of polynomials N(s) and D(s), called the numerator and denominator polynomials, respectively. You can represent linear systems as transfer functions in polynomial or factorized (zero-pole-gain) form. For example, the polynomial-form transfer function:
