Question 2
Consider the following statements:
1) The transfer function of a system is defined as the pseudo-static
relationship between the input and output variable.
2) We can compute the frequency response of an interconnected system of components with the help of Transfer functions.
3) While using the Laplace transform on a transfer function it is
possible to get information related to the qualitative behaviour of the response by solving for the dynamic response of the system
4) A transfer function is defined only for LTI systems when all initial conditions are assumed to be zero.
