1. The problem statement, all variables and given/known data Compute the DTFT of the following signal. [tex]x[n] = (0.8)^n u[n][/tex] 2. Relevant equations Properties of DTFT 3. The attempt at a solution Well, my professor tells me to use the properties of DTFT to solve this. I'd love to - except I don't know what the DTFT of [tex](0.8)^n[/tex] is. I've tried looking it up on the DTFT table, but couldn't find any, can someone tell me what it is?
