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
