• Consider the following ˜s(t) · exp(j2 f c t) = apple s I (t)+js Q (t) · apple cos(2 f c t)+j sin(2 f c t) • Real term apple ⇥ ˜s(t) · exp(j2 f c t) = s I (t) · cos(2 f c t) s Q (t) · sin(2 f c t) • Imaginary term apple ˜s(t) · exp(j2 f c t) = s I (t)sin(2 f c t)+s Q (t) cos(2 f c t) ˜s(t) X apple · s(t) exp(j2 f c t)
• Now consider ˜s(t) =s I (t)+js Q (t) =a(t)e j (t) where a(t) = q s 2 I (t)+js2 Q (t), (t) = tan 1 s Q(t) s I (t) • Then we can represent the modulated wave as apple s(t) = < apple = < ˜s(t)e j2⇥f ct a(t)e j[2⇥f ct+ (t)] = a(t) cos[2⇥f c t + (t)] apple = < a(t)e j (t) e j2⇥f ct
