HW7 discussion, ECE301 Spring 2011, Prof. Boutin
I think the table of DT Fourier Transform pairs has a mistake. where it says $ (n-1)a^nu[n] $ it should be $ (n+1)a^nu[n] $ instead according to the book and our notes.
- It's possible. Are you sure that your notes are correct? Can you find a way to double check? If so, then go ahead and change the formula in the table. It's a collective table after all!-pm
Can you provide an example of what we need to do for question 5?
- Look in your course notes. Locate the place where we got the expression for the frequency response from a difference equation. Look at all the steps we carried out in order to get that expression: to answer part a), just carry out these steps in reverse order. -pm
