uestion 1 (10 marks) (a) Relate the following parameters to each other with the aid of a diagram and using standard notation: impulse response, impulse function, and a linear time invariant (LTI) system Without knowing any details of an LTI system, what is the most convenient way of characterising the system? Why? Given an arbitrary input, describe three methods of evaluating the output of an L П system Use diagrams to explain if necessary Out of the three methods, it...
