1.	Assertion (A): Z-transform is used to analyze discrete time systems and it is also called pulsed transfer function approach.Reason (R): The sampled signal is assumed to be a train of impulses whose strengths, or areas, are equal to the continuous time signal at the sampling instants.(a) Both A and R are true and R is correct explanation of A(b) Both A and R are true and R is not correct Explanation of A(c) A is True and R is false(d) A is False and R is trueThis question was posed to me during an online exam.This is a very interesting question from The inverse z-transform and Response of Linear Discrete Systrems in section Digital Control Systems of Control Systems
Answer» Correct answer is (a) Both A and R are true and R is correct explanation of A The BEST explanation: Z-transform is USED to convert the discrete TIME systems into the z domain and it is also called pulsed TRANSFER function approach that is justified only at the sampling instants.
