n.信號分離

The paper also implements the DVB demultiplex receiving device. 針對以上情況，本論文提出了利用計(jì)算機(jī)接收DVB信號的可行性方案，并實(shí)現(xiàn)了相應(yīng)的DVB解復(fù)用接收器設(shè)備。

In seismic exploration, using SEG-D format is convenient and flexible, but this flexibility brings difficult in common use of demultiplex modular. 在地震勘探中,SEG-D格式使用方便、靈活,但其靈活卻為解編模塊的通用帶來較大的困難。

It shows that this kind of device can be tuned hundreds of nanometers.It can demultiplex any channel in all-wave fiber WDM in the future. 分析表明，它的調(diào)諧量可以達(dá)到數(shù)百納米，有望在將來的全波光纖WDM中對所有信道進(jìn)行解復(fù)用。

On the basis of introducing the standards of SEG-D format, we analyzed tape structure in SEG-D format and gave ordinary flow of demultiplex of SEG-D format tape. 我們在對SEG-D格式的標(biāo)準(zhǔn)進(jìn)行介紹的基礎(chǔ)上,分析了SEG-D格式的磁帶結(jié)構(gòu),給出了SEG-D格式磁帶解編的常規(guī)流程。

Demultiplex filter(usually refers to bandpass filter)is a significant part of DFDS,while the flat frequency response and linear phase characteristic in the passband of the FIR filter make it the best choice for the system. 分路濾波器 (通常是帶通濾波器 )是解調(diào)系統(tǒng)的重要組成部分 ,有限沖激響應(yīng) (FIR)數(shù)字濾波器具有平坦的通帶幅度響應(yīng)和線性相位特性 ,是數(shù)字式解調(diào)系統(tǒng)的最佳選擇。
