DSD Technology and Lossless Compression Algorithm in SACD

SACD中的DSD技术和数据无损压缩算法

As the SACD is increasingly popularized , the current mode power amplifier , compared with the prevalent voltage mode Hi-Fi power amplifier , will have a quick development and bright look in the future .

随着SACD的日益普及，同目前流行的电压模高保真功放的性能相比，电流模高保真声频功率放大器将会有美好的发展前景。

SACD is the improvement of CD in nowadays . It uses Direct Stream Digital ( DSD ) technology and Direct Stream Transfer ( DST ) lossless compression algorithm , to record audio data .

SACD是对现有CD的改进，它利用直接数字流（DSD）技术，和DST无损压缩方法，对数据进行存储。

In view of the contents and features of the overall design of antiaircraft missile , especially dynamic uncertainty of the design process , a new concept named self-adapting concurrent design ( SACD ) is proposed based upon the fundamental principle of concurrent design and adaptive control .

针对防空导弹总体设计的内容和特征，特别是其设计过程的动态不确定性，应用并行设计和自适应控制基本原理，提出了自适应并行设计的概念。
