2 y Pulse x y x z y y y -x y -y Next sllde… Pulse Reference Acquisition
Real part spectrum x y x cos z The reference phases were exactly along the Axis, thus phase difference between signal and reference was 0,π/2,π or 3π/2 y y sin If the phase difference was not integer multiple of π/2, then ? Next sllde… y -x -cos y -y -sin 12/28/2010 Dr.S.Aravamudhan
