Question

What is the condition of LTI system to be stable?

Answer 1

In signal processing, specifically control theory,bounded-input,bounded-output (BIBO) stability is a form of stability for linear signals that take inputs.If a system is BIBO stable,then the output will be bounded for every input to the system that is bounded.f or continuous-time signals .
hope it may help you

Answer 2

Answer:

An LTI system is stable if every bounded input produces a bounded output, i.e., is true for all t.
