Compute the DTFT of the following signal.
[tex]x[n] = (0.8)^n u[n][/tex]
Properties of DTFT
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?
