摘要 |
The invention relates to a method and an arrangement for digital/analog conversion in the return branch of an analog/digital modulator loop of an interpolative bandpass A/D converter. The D/A conversion is effected by a biphase interpolation. As a result, delay times up to 1.5 times the loop clock period are tolerated. The overall signal/noise ratio is better than in the case of rectangular interpolation. <IMAGE>
