Latest Patents
George C. Rosys holds a patent for a "Two State Phase Modulator with Minimum Amplitude Modulation." This invention relates to a two-state phase modulator that minimizes amplitude modulation. The modulator operates by assuming two phase states differing by .THETA., which is a sub-multiple of 180 degrees. This design allows for a phase variation of 180 degrees for phase-coded transmissions when the frequency of the phase-modulated carrier wave is multiplied by the reciprocal of the sub-multiple. The modulator derives three equal components: an in-phase component, an out-of-phase component, and a quadrature phase component. The out-of-phase component is delayed in relation to the in-phase component by .THETA./2, while the quadrature phase component is delayed by .THETA./4. The in-phase and out-of-phase components are reduced by a factor of (2 sin .THETA./2), ensuring that when added to the quadrature component, the resultants have a magnitude equal to that of the quadrature component and differ in phase by ±.THETA./2. The output of the modulator is formed by alternating the resultants with the quadrature component at zero phase during transitions. This innovative approach reduces amplitude variation during the phase modulation process to a fraction of a decibel.
