Unformatted text preview: In the frequency domain, the signal at point a’ can be written as Sa￿ (ω ) = j [M (ω + ω1 ) − M (ω − ω1 )]. 2 At point b, the signal becomes Sb￿ (ω ) = Sa￿ (ω )H (ω ) = And at point c Sc￿ (ω ) = j [M (ω + ω1 ) − M (ω − ω1 )]H (ω ). 2 1 ￿ 2π Sb (ω ) ∗ j π [δ (ω + ω2 ) − δ (ω − ω2 )] 1 = − 4 [M (ω + ω2 + ω1 ) − M (ω + ω2 − ω1 )]H (ω + ω2 )+ 1 4 [M (ω − ω2 + ω1 ) − M (ω − ω2 − ω1 )]H (ω − ω2 ). 1b - If the upper sign is chosen, the frequency-d...
