Dsbfc equation

WebThe quantity of interest is the phase of the modulation, φ mod, which is determined by the first two equations below. The third equation stems from the assumption that we have pure AM and that we can assume in-phase sidebands. φ mod up = φ up − φ c; φ mod lo = −(φ lo − φ c) φ mod lo − φ mod up = 0 ⇔ φ mod = φ mod lo = φ ...
