Abstract
Described herein is an apparatus including, a decoder that is configured to decode a digital control code. The digital control code corresponds to an intensity level control code of a plurality of LEDs. The apparatus includes a modulator that modulates a combination of the decoded control code and a dither signal, wherein the combined signal has a first modulation format. The apparatus also includes a converter that generates a dimming control signal by converting the first modulation format associated with the combined signal to a programmable second modulation format.
