1. A circuit for calculating a quadrature output having X and Y values from a quadrature input having X and Y values which define a point on a sinusoidal waveform, comprising:

  • a first scaling element configured to receive the input Y value and scale the input Y value by a scaling factor;

    a first adder configured to receive and add the input X value and the scaled Y value thereby producing the output X value;

    a second scaling element configured to receive the output X value and scale the output X value by the scaling factor; and

    a second adder configured to receive and add the input Y value and the scaled output X value thereby producing the output Y value;

    wherein the output X value and output Y value define a next point on the sinusoidal waveform.
