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.
举一反三
- One reversible continuous-time LTI system is cascaded with its reverse system, then the whole continuous-time system is one ( ) system A:
