1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution I'd like to see if I have the right line of thinking in my solutions: a. The sampling frequency should be such that no aliasing or folding occurs, so it should be twice the frequency of the original signal. $$x(t) = -17 -9sin(4\pi t) + 2.6sin(8\pi t) - 4cos(10\pi t)$$, I think sampled at 5Hz. b. There should now be four samples...but which four samples should I plot? c. There should be 2.5 samples right? Again how should I plot?
