  • Signal dependent dither
    Patent number: 7876247
    Abstract: A new technique on the dithering of one-dimensional signals is presented. The novel technique determines whether dither is needed when reducing the bit depth and evaluates whether the total error of the un-dithered quantization is white noise. If this is the case, then no undesired harmonics are added in the quantization or re-quantization process. The novel technique presents a state of the art signal-dependent dither having a lower quantization noise.
