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 true
Answer:A

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 true
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.
