1. A method of determining the instantaneous amplitude (a) and phase (φ

  • ) of a sinusoid comprising;

    A. digitizing said sinusoid to form a first signal which is the in-phase component (I) of said sinusoid;

    B. introducing a phase shift into said digitized sinusoid to produce the quadrature component (Q) of said sinusoid;

    C. processing said in-phase and quadrature components to compute the instantaneous phase (φ

    ) of said sinusoid; and

    D. processing said in-phase and quadrature components to compute the instantaneous amplitude (a) of said sinusoid;
