查询词典 analog signals

The signals were intercepted in the North Atlantic in 1942 and are believed to be unbroken.

这三条信息是盟军于 1942 年在北大西洋截获的，这些信息曾被认为是无法破解的信息。

This paper introduces the method of eliminating noise with attenuator. Each end of the specimen is covered with a metal cap and attenuators are inserted between metal caps and load platens. so noise is reliably eliminated, true AE signals of rock are detected and the reliablity and the precision of the data are improved.

本文介绍的衰减器排噪法，采用试件两端粘接金属端帽，加载压板与端帽之间安装衰减器，从而可靠地排除了噪音，检测到了岩石试件真实的声发射信号，提高了检测数据的可靠性和精度。

The results show that bandpass signals can be represented correctly with undersampling.

从实际的采样波形可以看出：欠采样完全可以反映出这些信号的特性。

Many signal processing algorithms aim at complex signals,so it is important to create complex signal from the bandpass real signal.

许多信号处理算法是针对复信号的，因此，从实带通信号中产生复信号是信号处理中的一个重要问题。

In this thesis, we proposed a robust trilateration method to estimate Path Loss Exponent which stands for the signal attenuate rate for each reference node to target path by using two different frequency signals and the trilateration method. Then we used every PLE to calculate the corresponding distance and performed the trilateration positioning task using these distances. We also ran two simulations to evaluate our proposed method.

但另一方面，即使在同一空间中，却因为存在著许多变数而导致各个不同的路径都拥有自己的路径衰减指数，所以此篇论文我们提出先利用两个不同频率的讯号测得参考点到目标上的路径衰减指数后，再利用此数值做此路径的距离推导，最后再藉由三点定位法做出目标的定位。

The equal distance 3-improved-coverage number of beacon sending position is presented according the acreage of ROI.Then a simple method is put forward to calculate the coordinates of the sending positions in rectangular ROI.Aiming at the shortage of the existent sequence algorithm,when beacon moves according to the path and emits RF signals at every position,the ant colony algorithm is applied to the position sequence so as to get the beacon sending position.Further,in this algorithm the sensors could work out their position with trilateration.

根据ROI面积给出了等距三重优化覆盖此ROI所需要的信标发射位置数量计算方法；随后对矩形ROI提出了一种简单的信标发射位置确定方法；针对现有的遍历发射位置点的路径遍历算法的不足，提出了一种新的应用蚁群算法的信标发射位置点的遍历算法，并利用该算法对基于三边测量方法进行传感器节点定位。

Many brain regions responded to top and bottom tooth pain — carried by signals from two distinct branches of a fiber called the trigeminal nerve — in the same way.

大脑的很多区域对上牙和下牙的疼痛作出反应。

17Minutes after launching, its first radio signals beeped to the tracking station in Manchester England.

发射后17分钟，它的第一组无线电信号就发送到了英国曼彻斯特的太空跟踪站。

Not knowing the distance, we don't know the time-lag in the signals, and cannot reconstruct the aliens' transmission.

这样的话我们就无法知道信号的准确时间差，也不能重建外星人传播的信号了。

It introduces the methods of how to extract characteristics of signals and how to design classifiers.

首先，本文引入了小波分析的概念，并详细叙述了它在调制类型识别方面的特点和优势。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。

Chillingly, he claimed our technology is 'not nearly as sophisticated' as theirs and "had they been hostile", he warned 'we would be been gone by now'.

令人毛骨悚然的，他声称我们的技术是'并不那么复杂，像他们一样，和"如果他们敌意"，他警告说，'我们将现在已经过去了。
