==AUDIO D/A CONVERTER - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240313802 titled 'AUDIO D/A CONVERTER

The abstract of this patent application describes an audio d/a converter that includes two segments with oversampling filters, multilevel modulators, and switching controllers to process PCM signals.

* The audio d/a converter consists of two segments, each with n elements.
* There are oversampling filters in each segment to process PCM signals.
* Multilevel modulators are used to process the output of the oversampling filters.
* Switching controllers are employed to control each segment of the d/a converter based on input signals.
