When the impulse response function h(t) is a causal signal, then the system is causal. Conversely, if the system impulse response is noncausal then the system is noncausal. To illustrate this important concept, consider two LTI systems that are represented by the impulse response functionsSystem 1: h1(t)=u(t) exp(-t)System 2: h2(t)=u(-t) exp(t)Specify whether or not the system is casual?
