ABSTRACT:
A frequency synthesizer is described illustrating a system and method for modulation. In particular, the frequency synthesizer includes a control circuit for producing a plurality of input signals that is scalable to a frequency profile. Each of the input signals includes a slope and a direction of the slope. An accumulator is coupled to the control circuit and receives the plurality of input signals. The accumulator sums the plurality of input signals to generate a standard curve. A frequency spreading control pattern generation modulator is coupled to the accumulator and modulates the standard curve to generate the desired frequency profile.
