Means for generating dither signals and the use of dither in multichannel quantizing systems are explored. After general recommendations are offered regarding the generation of suitable pseudorandom sequences for dithering purposes, efficient approaches to generating dither for use with multiple data channels are addressed. Practical properties required of multichannel dither signals are discussed, including the requirements that they render desired statistical properties of the total error signal in each channel independent of the input to that channel, and that errors in different channels be uncorrelated with one another. Methods of designing computationally efficient multichannel dither generation schemes meeting these criteria are presented with examples.
