Abstract
In a non-linear processing system, the main non-linear processing and filtering is performed with low precision in a separate branch. A low-precision version () of the input signal () is created in an extractor (), which is processed non-linearly in a low-precision non-linear processing unit () under constraints put on the non-linear processing. Quantisation errors or other artefacts, created by the use of low precision signals are finally removed by a precision restoring processing in a precision restoring unit () using the full-precision signal ().
