System for representasjon av data

摘要

A method and apparatus are disclosed for converting between samples of an input signal and an encoded signal composed of a plurality of component signals each representing a characteristic of the input signal in a different domain. The input signal is comprised of data samples organized into records of multiple samples, with each sample occupying a unique position within its record and each component signal is formed as the combination of a plurality of factors, each factor being the product of a score signal and a load signal. The score signal defines the variation of data samples from record to record and the load signal defines the relative variation of a subgroup of samples in different positions of a record.
