使用示波器测试数据部分的电路信号波形，使用网络分析仪测试丢包率、吞吐量、时延和背压等以太网指标的测试，并记录最终测试结果；电话部分主要是与台湾伟桥的FXO 3804和北京佳讯飞鸿的E1数字中继网关DT60，实现基于H.323协议的VoIP电话通信，同时介绍使用Ethereal软件和PA1688专用测试工具PalmTool的测试分析情况；电视部分主要是使用CATV频谱仪测试输出射频信号的平坦度、信号波形等分析信号质量，并通过实际电视接收观察输出的射频信号质量。

In SAR azimuth signal processing, it is very common to subsample the raw data with a filter, which may reduce the Signal Noise Ratio of the raw image.

摘要机载合成孔径雷达的方位向降采样经常会降低原始图像的信噪比。

By the use of this method, we can divide any ω-circulant signal into a summation of many sub-signals; especially among those sub-signals, there are many subseries of which their period is just equal to 1, which are actually the frequency elements of the original ω-circulant signal.

通过使用这种方法，我们可以将任意ω-循环信号分解成一序列子信号；特别地，这些子信号可以是周期为1的，这时的子信号实际上相当于Fourier变换中信号的频谱。

The signal components of interest in the interference frequency are also sunk while eliminating narrow band interference in direct sequence spread spectrum system by conventional NBI suppression techniques based on the estimator/subtracter in time domain, so the signal of interest is damnified inevitably.

传统的基于时域估计/相减的直接序列扩频系统窄带干扰抑制技术在对干扰陷波的同时，也将干扰频率处的信号分量陷去，不可避免地对有用信号产生损伤。

Realtime signal collection system is responsible to punctually sample from important devices, then convert the signals collected and store them through the measure of covering or superaddition in the realtime signal database.

监控图像显示系统可以对监控图像数据库中的图像数据进行显示和回放。

Superimposed signal is one of the most important signal version in practice.

叠加伩号是实际中常见的一种伩号形式，它的检测与估计在雷达、声纳、医学成像以及石油地球物理勘探等众多的领域中有着广泛的应用。

USB inserts signal "0" to avoid missing synch for long signal series of "1".

为了避免长"1"码影响同步信号的提取，USB采用了"0"翻转插入方式。

These special signal timing plans were developed for six incident conditions using the SYNCHRO signal timing software.

利用SYNCHRO信号配时软件建立6种交通事件情况下的信号配时方案。

A memory device includes: a generator system having a number of generators that supply voltage or current to the memory device, a controller that supplies to the generator system a state control signal that commands the generators to be in an active state or a standby state, and a self-refresh oscillator that generates a self-refresh clock signal having a period suitable to refresh memory cells of the memory device.

存储装置包括：具有多个发生器的发生器系统，所述多个发生器被配置来给所述存储装置提供电压或电流；给所述发生器系统提供状态控制信号的控制器，所述状态控制信号命令所述发生器处于激活状态或备用状态；以及自刷新振荡器，该自刷新振荡器生成具有适于刷新所述存储装置的存储单元的周期的自刷新时钟信号。

Only half of Nokia 6030- There are four signal input wires instead of two signal input wires in the second generation, which makes more brand cars available by easy connection without any teardown and adding any other parts.

只有一半诺基亚6030有四个输入信号而非电线电线两个信号输入的第二代这使更多品牌轿车方面没有任何可轻易拆卸、添加任何其他部分。

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。
