Consider the signal z(t) = 2 sin(wt +45°) + cos(wt). (a) Express r(t) in the form r(t)= Acos(wt + o). (b) Assume that w = 5. Make a plot of r(t) over one period. (c) Find a complex valued signal such that r(t)= R{z(t)}. Consider the signal z(t) = 2 sin(wt +45°) + cos(wt). (a) Express r(t) in the form r(t)= Acos(wt + o). (b) Assume that w = 5.
