无用信号

同时，设备也受到外来无用信号的影响&干扰。

Meanwhile , the equipment also is affected by outer useless signals & disturbance .

信号是传递信息的载体，但其往往夹杂着噪声及无用信号成分，因此必须将这些干扰成分滤除。

Signal is to transfer information carrier , but its often mixed with noise and useless signal components , and must therefore be these interference composition filter .

最后介绍了分选预处理器在电子战中的三种应用：威胁信号检测、无用信号滤波和脉冲重复频率选择滤波。

At last , the paper also presents three different applications of the sorting processor to electronic warfare : detection of threating signal , filtering of useless signal and PRF selection filtering .

为了提高产品的信噪比，这就要求在信号处理时通过滤波器滤掉无用信号保留有用信号。

In order to improve the signal-to-noise ratio of the product , a filter will be used to filter out useless signal and retain the useful signal in the process of the signal processing .

利用C语言编程，解决了一个限制提高和扩展XTCS存储性能的瓶颈，而且还添加了滤波程序，滤除其它无用的信号。

Using C language programming to solve bottleneck which has a limit to improve and expand XTCS storage performance , also adding a filtering process to filter out other unwanted signals .

在通信链路上出现的噪音或无用的信号，它损害语音、数据的接收或正确的解释。

On a communications link , noise or unwanted signals that impair the receipt or correct interpretation of speech or data .

滤波器是一种能使有用信号顺利通过而同时对无用频率信号进行抑制（或衰减）的电子装置。

Filter is a useful signal can pass while the frequency of the unwanted signal suppression ( or attenuation ) of the electronic devices .

微波光子学滤波器作为全光微波信号处理系统的核心器件，利用光纤和光器件使有用的微波信号通过而抑制噪声和无用的微波频率信号。

Microwave photonic filters are the key component in the system of photonic signal processing of microwave signals . It uses optical fiber and integrated photonic devices to carry out the filtering of clutter and noise from the wanted signal .
