  • Dithering technique for reducing digital interference
    Patent number: 8004436
    Abstract: The invention is directed to a circuit and method for equalizing digital interference. A digital interference equalizing circuit may include a signal clipping unit, receiving a digital signal and clipping the digital signal based upon a clipping function, and a dithering unit adding dither to the clipped digital signal. A digital interference equalizing circuit may also include a noise detection circuit, detecting the normal activity level in a digital signal which may then be used to scale the dither added to the digital signal.
    Type: Grant
