Write your questions/comments here.
Question 1 i's) I am a little shaky as to the mathematical procedure for proving an LTI system is memoryless using its impulse response. The notes say $ h(t) = k\delta(t), k \in $ complex, but I am not sure how to use this...
- Just check if h(t) has the correct form. Say, for example if h(t)=$ \delta(t+7) $, then it does not have the right form, so the system is not memoryless. -pm
Question 2 h) No matter how I think about this signal, I think that it's always 1, and therefore not periodic, so it doesn't have fourier coefficients. What am I doing wrong?
- Nothing! There was a typo in the question. It has been corrected now. -pm
Question 6) Should there be j's in parts c,d,e? Because if not, they're not periodic...
- You are absolutely right. This has been corrected. -pm
