Q1: which of these statements are True and which one is False? * 1. Without the knowledge of the ROC, there is no unique relationship between a sequence and its z-transform. 2. The gain margin is the change in closed-loop gain, expressed in decibels (dB), required at 180 o of phase shift to make the closed- loop system unstable. 3. The phase margin is the change in open-loop phase shift, required at unity gain to make the closed-loop system unstable. 4. A discrete-time linear system is BIBO stable if and only if its impulse response sequence is stable. 5(z-2) (z-0.1)(z-0.8) 5. The system has transfer function such as G(s) = would be stable.
