Abstract:
A method of generating a spread spectrum signal is disclosed. The method includes selecting a first pseudorandom slope for a modulation curve. A current frequency on the modulation curve is selected. An oscillating signal is produced at the current frequency for a respective time. The current frequency is set to a next frequency on the modulation curve. The steps of producing an oscillating frequency and setting the current frequency to a next frequency are repeated until the current frequency is a final frequency on the modulation curve.
