Suppose a system with input x(t) and output y(t) is given by the following differential equation dy(t) dy(t) - 2y(t) = x(t) dt² dt (a) Let h(t) denote the impulse response of the system. Determine H(s), the Laplace transform of h(t). What are the poles and zeros of H(s)? (b) Determine h(t) when the system is stable. (c) Determine h(t) when the system is causal. (d) Determine h(t) when the system is neither stable nor causal. (e) When the system is causal, draw a block diagram of the system.
