Complex numbers and signal processing homework

Resolve 4 mathematics questions about complex numbers and signal processing. The questions details are in the linked documents. Here is an overview : - Find all the complex numbers roots of n^e (resolve Z^n = 1) and represent them in the complex plane: a) n = 4 b) n = 8 c) n = 16 - Give a graphical representation of the following signals : (6 signals) - For each of the following signals, determine if they have a period or if they are aperiodic. If they have a period, give the signal period. If needed, give the graphical representation (5 signals) - Calculate and draw yn = xn * hn for the following signals (2 signals). *** The project must be completed within the next hours.
