  • D/A conversion method and apparatus
    Patent number: 6433718
    Abstract: A D/A conversion system includes means for arranging a stream of digital samples into frames, each frame including a guard time period. Means are provided for determining a measure of the overall magnitude of digital samples in each frame. Means increase the magnitude of all samples of frames that have a measure that falls below a predetermined threshold by shifting the samples a common number of bits. A D/A converter converts frames with shifted and frames with unshifted samples. An attenuator attenuates the D/A converted samples of frames with shifted samples to compensate for the magnitude increase.

  • D/A conversion method and apparatus
    Publication number: 20010017596
    Abstract: A D/A conversion system includes means (18) for arranging a stream of digital samples into frames, each frame including a guard time period. Means (52) are provided for determining a measure of the overall magnitude of digital samples in each frame. Means (50) increase the magnitude of all samples of frames that have a measure that falls below a predetermined threshold by shifting the samples a common number of bits. A D/A converter converts frames with shifted and frames with unshifted samples. An attenuator (54) attenuates the D/A converted samples of frames with shifted samples to compensate for the magnitude increase.
