Usually point a kind of inside to pack the arithmetic figure cent the network with the box of the power enlarger . arithmetic figure type the power enlarger for method for signal for inputting for arithmetic figure comparing , at with arithmetic figure signal handling again and again partitioning the empress , then and respectively these signals transformation is imitating the signal , then again from eachly from of box enlarge the empress to go to again to push the the cowgirl in the box to pronounce the unit 通常指一种内装数字分频网络和功率放大器的音箱。数字式音箱输入的信号为数字比特流,在用数字信号处理的方法将音频频谱分割后,便分别将这些信号变换为模拟信号,然后再由各自的功率放大器放大后再去推动音箱中的相应发音单元。
Using the idea of multiscale analysis and by combining the model - based analysis method for dynamic systems with the multiscale signal transformation method , we put forward a new algorithm of multiscale distributed information fusion estimation . for multi - model dynamic systems having different description for target state at different scales , at the finest scale we can obtain the optimal fusion estimates based on global information , which give a primary solution to the information fusion estimation of multiscale dynamic systems . this work enriches and develops the information fusion theory 利用多尺度分析的思想,将基于模型的动态系统分析方法与基于统计特性的多尺度信号变换方法相结合,在不同尺度上拥有对目标状态进行不同描述的多模型动态系统,提出多尺度分布式信息融合估计新算法,在最细尺度上获得目标状态基于全局信息的融合估计值,初步解决了多尺度动态模型信息融合问题,这些工作丰富和发展了信息融合理论
