查询词典 bandwidth

With increasing frequency and adding bandwidth, design of RF circuit is harder and harder.

随着频率的提高和带宽的增加，射频前端的设计越来越困难。

According to the linear-modeling of the PLL, the bandwidth should be large to achieve fast locking and be small to reduce the ripple on the control voltage while the whole loop is near or in the state of lock.

因此设计适合条件的线性模式锁相回路，须设计较大的频宽使其能快速锁定电路，并在锁相回路整体回路接近锁定状态时使影响振荡器输入电压控制线之扰动减少。

The ROLF is divided into slow and rapid ROLF in terms of the FORR time parameters, the round-trip time and response time equal to the reciprocal of the effective bandwidth.

在上述的理论和实验研究中，本文取得以下主要进展 1首次证明了环形腔的有效带宽总是大于入射光的频宽，这一结果确定了环形腔的最大分辨本领。

The RRM based on bandwidth is an effective approach for this challenge, which is also becoming the research hotspot at present.

基于带宽按需分配的卫星无线资源管理机制是一个有效的解决途径与发展方向，也是目前研究的热点。

Then there are the costs of running such a site—video requires a lot of bandwidth and storage.

此外还有经营此类站点的费用问题——视频文件需要较大带宽和储存空间。

This architecture has higher salability ,saves network bandwidth,relieves server load.

该体系结构具有较高的可伸缩性，可节省网络带宽、减轻服务器负载。

ABSTRACT:The half-power bandwidth method is the commonly used method at home and abroad, the authors discover that factors, such as the sampling frequency, the frequency resolution, the ratio of the sampling frequency to the signal frequency, the analyzed width and the damping ratio, make the estimated damping ratio fluctuate vastly. Mostly the result is incredible except for some conditions, the error is sometime amazing, which is not acceptable.

半功率带宽法是国内外常用的测试阻尼的方法，笔者发现半功率带宽法由于受到信号处理中的①采样频率SF②频率分辨率△f③采样频率与信号频率之比K ④采样分析的长度T和⑤阻尼比D的大小等因素的影响使得测得的阻尼比值波动很大，除少数状态是可信的外，多数状态是不稳定的，有时误差惊人，得到的测试数据不能使用，易导致错误的结论。

The market almost every day there are new products, they have a bigger screen, more memory, higher bandwidth, faster processor.

市场上几乎每天都会有新产品出现，它们有着更大的屏幕，更大的内存，更高的带宽、更快的处理器。

In addition, to reduce the scheduling overhead, the DBA scheme utilizes a novel different cycle policy which involves selective bandwidth allocations to different service classes based on their delay bounds.

此外，为了减少调度开销，该DBA方案利用了一种不同的新型轮询的方案，它基于一定得时延范围内有选择性将带宽分配给 www.51lunwen.com 不同的服务等级。

A charge pump phase locked loop based on self biased technique is presented. In this technique, the operating bias levels are essentially established by the operating frequency of the voltage controlled oscillator, namely, all bias voltages and currents are determined by VCO controlling voltage. Thus, a fixed damping factor and a fixed ratio of the bandwidth to operating frequency are obtained, which are defined by th...

给出了基于自偏置技术的电荷泵锁相环电路，压控振荡器的工作频率动态地建立了电路内部所有的偏置电压和电流，从而实现了固定衰减因子，固定环路带宽与工作频率之比，这二者由电容的比率决定，极大地实现了电路设计的工艺无关性，同时也得到了小的相位抖动，最后，对这种锁相环的稳定性进行了一定的分析。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
