Question A - Periodic Signals Revisited
I chose to use the CT (continuous time)periodic signal: y(t) = cos(t). The signal can be expressed as both periodic and non-periodic in DT (discrete time).
Discrete Time, Non-Periodic: Cos[n] is non-periodic since it doesn't satisfy the equation a[n + T] = a[n] for an integer T.
Discrete Time, Periodic:
