ABSTRACT:
Universal signal modulators structures are shown which are particularly useful for selectively generating polar-modulated digital sequences from input phase and amplitude symbols and for generating quadrature-modulated digital sequences from input first and second quadrature symbols. Significantly, the modulation structure (quadrature modulation or polar modulation) of these embodiments can selected by simply changing the state of a mode command.
