1. The problem statement, all variables and given/known data See figure attached. 2. Relevant equations 3. The attempt at a solution I'm quite sure what he's getting at with this problem... The minimum sampling frequency would be 2 times the maximum frequency component of the signal. Since this is a sinusoidal signal, it should only have 1 frequency component, that is ωo which in our case is a mess of a's and k's. Can someone give me a nudge in the right direction, or clarify what needs to be done? Thanks again!
