![]() The region of convergence must therefore include the unit circle. A system is BIBO stable if every bounded input signal results in a bounded output signal, where boundedness is the property that the absolute value of a signal. Time-domain condition for linear time-invariant systems Continuous-time necessary and sufficient condition įor a continuous time linear time-invariant (LTI) system, the condition for BIBO stability is that the impulse response, h ( t ). If the conditions of the first item are satisfied the system is BIBO stable (bounded input/bounded output stable), i. ![]() Bounded input, bounded output (BIBO) stability is a form of stability often used for signal. hi i 0 4 13 Proof of Necessity (Only if) Assume the system is BIBO stable but the impulse response is not absolutely summable. BIBO stable is a condition such that any bounded input yields a bounded output. Theorem 4.2:BIBO Stability A discrete-time linear system is BIBO stable if and only if its impulse response sequence is absolutely summable i.e. BIBO Stability Is system BIBO stable if its impulse response h(k) is bounded NO Bounded & strictly positive impulse response yk hk iui k i k. ![]()
