3. You are given the LTI system with impulse response h(t)=2eu(t) and the signal expression x(t) =28(t– 1)+3 sin(2nt) 3.a) Check whether the system is causal and stable (You must justify your answer)...

Please help with the solution to this problem.

You are given the LTI system with impulse response h(t)=2eu(t) and the signal expression x(t) =28(t– 1)+3 sin(2nt) 3.a) Check whether the system is causal and stable (You must justify your answer) 3.b) Evaluate whether the signal x(t) is periodic. If the signal is periodic compute the period. 3.c) Compute the output of the system when the input signal is x(t).
