1.	Assertion (A): The signals a^nu(n) and a^nu(-n-1) have the same Z transform, z/(z-a)Reason (R): the region of convergence of a^nu(n) is \|z\|>\|a\|, whereas the ROC for a^nu(-n-1) is \|z\|(a) Both A and R are true and R is correct explanation of A(b) Both A and R are true but R is not correct explanationof A(c) A is true but R is false(d) A is false but R is trueThis question was posed to me during an interview for a job.I'm obligated to ask this question of The Z-Transfer Function in portion Digital Control Systems of Control Systems
Answer» Right ANSWER is (d) A is false but R is true The best I can explain: Both have the ROC as given in the reason is true but the z TRANSFORM for the SECOND is with a MINUS SIGN.
