I just started my discrete time class and the book is really horrible at explaining stuff. Im stuck on the first problem which is just like the rest so does anyone have any idea how to do this (it looks like its really easy)
Set up an expression for the signal using a digital freqency F < .5 for x[n]=cos(4n*pi/3)
I figure If I can get some help with how to solve the first one, the rest should make sense too.
