a) Using mathematical formulations distinguish between period signals and non-periodic signals. Determine whether the signals below are period signals or non-periodic signals. If a signal is periodic signal find its period i) x(t)=Sin²(n/4) ii) Cos (3)¹2t+Sint Major Topic Periodic and Non-periodic Signals Major Topic Energy and Power Signals Blooms Designation EV b) Differentiate between an energy signal and a power signal.
