目前国产高频宽带扫频仪的对数放大器性能还有待提高。
The properties of domestic high-frequency broadband sweeper, for instance, the dynamic range, logarithmic accuracy, flatness and log linear, still need to be improved.
在本论文中，我们采用高频宽效率的正交分频多工调变系统。
In this thesis, we adopt the bandwidth-efficient OFDM system, which can adjust efficiency of bandwidth usage.
这项策略最适合高频宽网路连接，因为在低频宽连接上启动应用程序的延迟时间可能会非常久。
This strategy works best for high-bandwidth network connections; the delay in starting the application may be unacceptably long over low-bandwidth connections.
例如，您可记录网路的高频宽使用率和低频宽使用率的时间，以确保系统进程(如备份)不会干预使用者活动。
For example, you could note high and low bandwidth-utilization times for your network to ensure that systems processes such as backups don't interfere with user activities.
这一过程的一个主要特点是，它同时生产PNP和NPN晶体管，这使得高频宽带设计，如在HA- 5033，实用。
A major feature of this process is that it produces both PNP and NPN high frequency transistors which makes wide bandwidth designs, such as the HA-5033, practical.
ADSL技术是一种调制技术，在双绞铜线的两端分别接入adsl调制解调器，即可利用其高频宽带特性传送高速数据。
ADSL is one of the modulation techniques. Using the wideband capacity in copper twisted-pair cable, high speed data can be transmitted on the subscriber line.
