AUDIO D/A CONVERTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18606487 titled 'AUDIO D/A CONVERTER
The abstract of the patent application describes an audio D/A converter with multiple elements including oversampling filters, multilevel ΔΣ modulators, and switching controllers.
- The audio D/A converter consists of two segments, each with N elements.
- The first oversampling filter processes a PCM signal before it is fed into the first multilevel ΔΣ modulator.
- The second oversampling filter also processes a PCM signal before it is fed into the second multilevel ΔΣ modulator.
- The first and second switching controllers are responsible for controlling the first and second segment D/A converters based on their respective inputs.
Potential Applications: - High-quality audio playback systems - Digital audio processing equipment - Audio production and recording devices
Problems Solved: - Improved audio signal processing and conversion - Enhanced audio quality and fidelity - Efficient control and management of D/A conversion processes
Benefits: - Higher resolution audio output - Reduced noise and distortion - Precise control over audio signal conversion
Commercial Applications: Title: Advanced Audio D/A Converter for High-Fidelity Systems This technology can be utilized in high-end audio equipment, professional recording studios, and consumer electronics for superior audio performance.
Questions about the technology: 1. How does the multilevel ΔΣ modulator improve audio signal processing? 2. What are the advantages of using oversampling filters in the D/A conversion process?
Original Abstract Submitted
An audio D/A converter includes: a first segment D/A converter including N elements; a second segment D/A converter including N elements; a first oversampling filter configured to process a PCM signal; a second oversampling filter configured to process a PCM signal; a first multilevel ΔΣ modulator configured to process an output of the first oversampling filter; a second multilevel ΔΣ modulator configured to process an output of the second oversampling filter; a first switching controller configured to control the first segment D/A converter according to an input to the first switching controller; and a second switching controller configured to control the second segment D/A converter according to an input to the second switching controller.
