| 摘要 |
<p>A switching device for switching between a 1-bit digital signal SIGMA DELTA modulated by a first sampling frequency and a 1-bit digital signal SIGMA DELTA modulated by a second sampling frequency lower than said first sampling frequency. The 1-bit digital signal SIGMA DELTA modulated by the second sampling frequency is transiently converted to the 1-bit digital signal SIGMA DELTA modulated by the first sampling frequency. The converted 1-bit digital signal or the 1-bit digital signal SIGMA DELTA modulated by the first sampling frequency is switched by cross-fading processing for realizing switching with suppressed noise generation at the time of switching. <IMAGE></p> |
