CSE4050 Signals and Systems for Computer Eng. Homework \#4 1) Consider a discrete-time LTI system with impulse response h(n)=1/5[(n+2)+(n+1)+(n)+(n1)+(n2)]=u(n+2)u(n3) Compute the output signal y(n) of this system when the input is x(n)=(1/3)nu(n) 2) Discuss if the above LTI system is; -- with memory -- causal -- stable -- FIR/IIR.
