Method and apparatus for suppressing quantization noise in digital-to-analog conversion through dual-path signal processing with frequency-selective filtering.

Patentradars sammanfattning

The invention relates to quantization noise suppression in signal processing systems, specifically in the H04B 1/04 domain of digital transmission. A dual-path architecture is employed where a first signal path includes a DAC and filter to remove quantization noise components in a target frequency band, while a second signal path processes a derived digital signal through a separate DAC. This approach enables selective noise suppression while maintaining signal integrity across multiple frequency bands.
