For each of the systems in Figure P2.26, pick the strongest valid conclusion that you can make about each system from the following list of statements:

(i) The system must be LTI and is uniquely specified by the information given.

(ii) The system must be LTI, but cannot be uniquely determined from the information given.

(iii) The system could be LTI and if it is, the information given uniquely specifies the system.

(iv) The system could be LTI, but cannot be uniquely determined from the information given.

(v) The system could not possibly be LTI.

For each system for which you choose option (i) or (iii), give the impulse response h[n] for the uniquely specified LTI system. One example of an input and its corresponding output are shown for each system.
