Consider a continuous-time LTI system with impulse response given by h(t) = u(t) u(t 2) where u(t) is the unit step function. (a) Is this system stable? Justify your answer. (b) Sketch the output of this system given the input x(t) = ?(t)(t1), where ?(t) is the unit impulse function. (c) Find the frequency response H(j!) for this system.
