  • Abstract
    This paper derives fs/2 modulation from signal and system theory of complex signals. It is presented, how the In phase and the Quadrature phase are reduced to a single phase, while all properties of complex signaling are maintained. Further, it is derived, that the remaining phase is predestinated for ΣΔ modulation. Finally, simulation results prove the theoretically derived offset-elimination property.
