SHORT QUESTIONS AND ANSWERS
Q1. What do you mean by transfer function of a system?
Ans.: It is defined by the ratio of Laplace transform of output response to Laplace transform of input (excitation) assuming all the initial conditions to be zero.
Q2. What do you mean by characteristic equation of a system?
Ans.: The denominator polynomial in terms of s of a transfer function is known as characteristic polynomial. If this polynomial is equated to zero, characteristic equation will be obtained.
