ABSTRACT:
A frequency synthesizer is described illustrating a method for modulation having an adjustable standard curve used to modulate an input signal for spread spectrum modulation. In particular, the a standard curve is generated, wherein the standard curve modulates an input signal to generate a spread spectrum of frequencies. The standard curve is associated with a standard modulation frequency. The standard curve is sampled at a constant sampling frequency. A shape of the standard curve is adjusted, such that critical points of the standard curve are captured when sampling the standard curve. The shape of said standard curve that is altered varies between at least two periods.
