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.
Potential Applications: - High-quality audio equipment - Digital audio processing systems - Consumer electronics
Problems Solved: - Improved audio signal processing - Enhanced audio quality - Efficient conversion of digital to analog signals
Benefits: - High-fidelity audio output - Precise signal processing - Enhanced user experience
Commercial Applications: Title: Advanced Audio Processing Technology for High-End Audio Equipment This technology can be used in high-end audio systems, professional audio equipment, and consumer electronics to provide superior audio quality and performance.
Questions about the technology: 1. How does this audio d/a converter improve audio quality compared to traditional converters? - The use of oversampling filters and multilevel modulators enhances signal processing and fidelity, resulting in superior audio output. 2. What are the potential cost implications of implementing this technology in audio equipment? - While the initial cost may be higher due to the advanced components, the improved audio quality and performance justify the investment over time.
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 �� modulator configured to process an output of the first oversampling filter; a second multilevel �� 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.
