Finally, a better digital pulling method, pulling by digital differential synchro( DDS) is given. 提出了一种更好的数拖方案——数字差动同步机接口法。
The analysis of DDS output spectrum in presence of phase truncation is made with breaking its waveform in timedomain and a fast arithmetic is presented which makes it easy to compute the error spectrum caused by phase truncati 采用时域波形分解的方法,分析了相位截尾对DDS输出频谱的影响,给出了相位截尾误差频谱的分布规律,提出一组误差谱的高精度快速算法,并对其作了仿真,波形数据表地址字长较长时,可采用其中的近似算法,较短时则可采用精确算法.
dds
[ noun ] a doctor's degree in dental surgery <noun.communication>
Mr Brian Eadie, formerly Software Partnership's sales director, is now sales development director for the group. Mr James McGowan, DDS chief executive, emphasised the synergy between the two companies.
