Question

The impulse response of a LTI system is a unit step function, then the corresponding transfer function is

(a) 1/s

(b) 1/s^2

(c) 1

(d) s

I have been asked this question in class test.

I'm obligated to ask this question of Experimentation of Transfer Function topic in portion Frequency Response Analysis of Control Systems

Answer 1

Correct choice is (a) 1/s

The best explanation: The impulse response of a LTI system is the transfer function itself and hence for the unit step function . As input then the transfer function will be 1/s.
