查询词典 transmitter-receiver

Since there is frequently no LoS between the transmitter and the receiver, tously described phenomena. Therefore, the received signal level is quite var

由于通常在收发信机之间没有直达路径，接收信号通常是若干分量的合成结果，而这些

It can been used for the have line stereo headphone with microphone a. Switch "of" the transmitter and the neckband receiver unit b. plug the input sound source line with the 3.5mm jack and microphone to headphone mput jack Adapt the 3.5mm plug into the 3.5mm to RCA plug adaptor if necessary depending on the audio sound Make sure that the output sound source is from AUDIO OUT of your TV or Audio equipment c. Open the variator to the niche

它可以被用来为有线立体声耳机与麦克风甲开关&的&发射机和接收机领口股乙插头输入音源线与3.5毫米插孔和麦克风耳机mput杰克适应3.5毫米插头到3.5毫米到的rca插头电源适配器，如果有必要视音频健全确保输出声源，是从音频输出你的电视或音响设备长打开variator向利基

The unit's transmitter sends out pulses of ultrasonic waves at the same frequency as the bat, and the receiver picks up the returning echoes, Because these are still above the frequency at which the human ear can pick them up, the echoes are filtered through circuits which turn them int clearly audible 'bleeps' before passing them into headphones.

由于这些仍是在频率上超过了人耳的可闻范围，回波在送到耳机之前通过电路滤波，这个电路把回波转化为清晰可听的信号声。

These Lorenz systems are built, which are relevant and can be switched each other via the choicer. Chaotic synchronization of these systems is realized using same nonlinear feedback control method. The transmitter can be switched discretionarily among several chaotic systems, bring on ceaseless changing of the chaotic carriers in transport channel. In the receiver, the chaotic carriers are retrieved from the received signals, then the information signals are recovered.

构建了有一定关联的两个Lorenz混沌系统，并通过选择器在系统间随机切换；用同一种控制方法既能实现不同Lorenz系统的混沌同步，又能实现相同Lorenz系统的混沌同步；发送系统可以在Lorenz混沌系统间随机转换，传输信道中混沌调制信号也随之不断变化；接收系统将混沌调制信号解调后，即可获取有用信号。

The transmitter takes advantage of the eigenvectors of the SCM of the correlated channels to spread and weigh the signals of each layer. The spatial eigenbeams are formed to carry the signals being spread. The receiver distinguishes the signals from different beams via dispreading operations; therefore co-channel interferences are eliminated effectively.

发射机利用信道空域协方差矩阵的特征矢量，对每一层发射码元进行扩频和特征波束形成加权，形成正交的空域特征波束来承载扩频后的信号码元；接收机则通过解扩处理分离来自不同波束上的信号，有效地抑制了共信道干扰。

Early used to detect objects without photoelectric sensor is a small metal cylindrical equipment, with a camera calibration transmitter, will focus on optical receivers, the receiver will be receiving a cable superimposes the vacuum tube amplifiers.

早期的用来检测物体有无的光电传感器是一种小的金属圆柱形设备，发射器带一个校准镜头，将光聚焦射向接收器，接收器出电缆将这套装置接到一个真空管放大器上。

In order to fulfil the requirements for measuring radiation and insertion loss characteristic of smoke screen at 3mm band, an automatic measurement system, including a transmitter and an integrated 3mm band radiometer/receiver is developed.

为了满足3mm波段烟幕辐射特性和插入损耗特性测量的需要，研制了3mm波段烟幕特性自动测量系统-3mm辐射源和3mm辐射计／接收机一体机。

The "main frame" unit on board ships contains the timer, transmitter, receiver, power supply and transmit-receive "duplexer" function of the antenna system.

计时器则通常包含在舰艇的&主机&里，发射机，接收器，动力供应以及收发双工功能位于天线系统。

Tofind a target and determine its position,any radar station has to basically consist of a transmitter,a receiver,an antenna,an antenna duplexer,a display and a timer.

为了要发现目标和确定其位置，任何雷达站基本上都必须包括发射机、接收机、天线、天线转换开关、显示器和定时装置。

You can always unload your troubles on Mary, she is your good friend and will listen to you.

你可随时向玛丽倾吐你的烦恼，她是你的好朋友，会听你倾诉的。
