Consider the following three impulse responses: hi(t)- ut) h2(t)2(t) +5e2u(t) using the ctft, do the following. 1. find the output of these systems to the input cos(t) 2. find the output of these systems to the input cos(2t). 3. find another system whose output with input cos(t) is the same as hi(t) 4. find another system whose output with input cos(2t) is the same as h2(t) what this means is that if you have an lti system with a wire going in and a wire going out, just looking at the output to a single cosine input will not let you figure out ("identify") the system impulse response.
