\sectionLinear Time-Invariant (LTI) Systems and Convolution

\subsection*Solution Stability: \(\int_-\infty^\infty |h(t)| dt = \int_-\infty^\infty e^- dt = 2\int_0^\infty e^-t dt = 2\). Finite ⇒ stable. \\ Causality: \(h(t) \neq 0\) for \(t<0\) ⇒ not causal. signals and systems problems and solutions pdf
