Patent ID: 7317413

Claim:
A system for generating an analog output from a digital input signal at a sampling rate, the system comprising: a data decomposer operative to generate a set of first data sub-samples based on a first data sample of a first digital signal derived from the digital input signal, wherein a value of the first data sample has a corresponding normalized range, wherein a value of each first data sub-sample has a corresponding normalized range, wherein the normalized range of the value of the first data sample is greater than the normalized range of the value of each respective first data sub-sample, and wherein the data decomposer includes: a pre-decomposing processor operative to generate a second data sample based on the first data sample, a value of the second data sample having a corresponding normalized range; a data decomposing processor operative to generate a set of second data sub-samples based on the second data sample, a value of each second data sub-sample having a corresponding normalized range, wherein the normalized range of the value of the second data sample is greater than the normalized range of the value of each respective second data sub-sample, and wherein a sum of the values of the set of second data sub-samples is equal to the value of the second data sample; and a post-decomposing processor operative to generate the set of first data sub-samples based on the set of second data sub-samples; and a plurality of D/A converters, each D/A converter being associated with a respective one of the set of first data sub-samples, each D/A converter being operative to receive the respective first data sub-sample associated therewith, and to generate a respective one of a plurality of analog component outputs singly or jointly with at least one of the other D/A converters, whereby the analog output is produced by additively combining the plurality of analog component outputs.
