Digital-to-analog converter including integral digital audio filter |
摘要 |
A digital signal processor (DSP) circuit is configured to recursively retrieve and process pairs of data points in a symmetric digital filter. The data points are retrieved from an external source (e.g., compact disk) at a first frequency, and processed within the DSP at a second frequency. The DSP employs a floating pointer scheme, which effectively functions a buffer to thereby compensate for jitter or drift between the first and second frequencies.
