Problem 7 [2.5 pts]
The response of an LTI system to u[n+2]
appears to be the following sequence.
-3-2-101234
Do we have enough information to determine the impulse response of this system? If so, derive
it and plot it. If not, explain why.
Problem 4
5'
Consider the systems S₁(x[n]) = x[n]+5[n²−1] and S2(x[n]) = x[n(n−2)].
a [2 pts] Plot the impulse responses of S₁ and S2, respectively.
b [2.5 pts] Determine whether S₁ and S2 are causal. Justify your answer in details.
Warning: There will be no credit for just 'yes' or 'no' answer.
