Problem
(a) Give an example of a power signal and one example of an energy signal.
(b) Given a periodic signal x (t) = A sin (2Bft). Calculate the power Px.
(c) Differentiate between baseband and bandpass signals.
(d) Consider the linear system represented in Figure.
Given x(t) = cos( 2Bf1t) ; h(t) = t for 0 <= t <= T and h(t) =0 elsewhere Find y(t).
(e) Find the Fourier Transform of the signal in Figure
(f) An energy spectrum has a peak value of 0.02. Find the value the energy spectrum must go below to be
