Determine Determine which of the following statements concerning LTI systems is false. A: If h(t) is the impulse response of an LTI system and h(t) is periodic and nonzero, the system is unstable. B: If a discrete-time LTI system has an impulse response h[n] of finite duration, the system is stable C: If an LTI system is causal, it is stable D: A continuous-time LTI system is stable if and only if its impulse response h(t) is absolutely integrable.
