Four systems have the following impulse responses. For each one sketch its impulse response, then draw its pole-zero plot and region of convergence. For each one also determine whether the system is causal and whether it is stable. (a) h1(t) e u(t) (b) h2(t) eu-t)
A continuous-time LTI system has unit impulse response h(t). The
Laplace transform of h(t), also called the “transfer function” of
the LTI system, is
