Why do we need transfer function?
A transfer function is a convenient way to represent a linear, time-invariant system in terms of its input-output relationship. The key advantage of transfer functions is that they allow engineers to use simple algebraic equations instead of complex differential equations for analyzing and designing systems.Click to see full answer.

A transfer function is a convenient way to represent a linear, time-invariant system in terms of its input-output relationship. The key advantage of transfer functions is that they allow engineers to use simple algebraic equations instead of complex differential equations for analyzing and designing systems.Click to see full answer. Similarly one may ask, what does transfer function mean?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.Subsequently, question is, 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). Likewise, people ask, what are the advantages of transfer function? One advantage of transfer function analysis is that the output can be easily determined for any given input. Another advantage is that complex differential and integral equations are transformed into simple and easy algebraic equations.What is the gain of a transfer function?The value out the front of the transfer function when in terms of root natural frequencies is usually called the “gain” because when there is no pole at zero it is equal to the DC gain. That’s one of the benefits of expressing the function in that form – you can read the DC gain straight from the expression.
