The paper also implements the DVB demultiplex receiving device. 针对以上情况，本论文提出了利用计算机接收DVB信号的可行性方案，并实现了相应的DVB解复用接收器设备。

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、灵活,但其灵活却为解编模块的通用带来较大的困难。

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，它的调谐量可以达到数百纳米，有望在将来的全波光纤WDM中对所有信道进行解复用。

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. 我们在对SEG-D格式的标准进行介绍的基础上,分析了SEG-D格式的磁带结构,给出了SEG-D格式磁带解编的常规流程。

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. 分路滤波器 (通常是带通滤波器 )是解调系统的重要组成部分 ,有限冲激响应 (FIR)数字滤波器具有平坦的通带幅度响应和线性相位特性 ,是数字式解调系统的最佳选择。
