Which of the following is a transfer function?
Detailed Solution. Concept: A transfer function is defined as the ratio of the Laplace transform of the output to the Laplace transform of the input by assuming initial conditions are zero. Therefore, the transfer function is also known as the impulse response of the system.
What does a transfer function describe?
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.
What is the transfer function formula?
Characteristic equation of a transfer function -
Here, the characteristic equation of a linear system can be obtained by equating the denominator to the polynomial of a transfer function is zero. Thus the characteristic equation of the transfer function of Eq.1 will be: an sn+a(n-1) s(n-1)+.........+a1 s+a0=0.
