LTI System

Which of the following can be true about an LTI system described by the following system function? H(z) = 222–12z+1 6z2 –5z+1 a. The system is anticausal and stable. b. None of the other choices c. The system is causal and stable. O d. The system is noncausal and stable. Determine the impulse response of the digital filter described by the following difference equation: ут] — ах(п — 2] + by|n — 1]. O a. h(n] = ab7–2u[n – 2] O b. h(n] = ab"-lu[n – 1] O c. h(n] = (ab)"-²u[n – 2] O d. h[n] = abu[n – 2] 2-2
