The next in order, at the back half of this text, studies the design of transmitter amplifier .

其次，在本文后半部分主要研究发射机放大器的设计。

Controls on the transmitter allow you to adjust the distance between where the beeping starts and the shock occurs.

控制对发射机，让你调整它们之间的距离的地方会发出哔声开始和休克发生。

On the basis of recent research, this thesis concentrates on bellowed several aspects to do some research of high-speed transmitter.

在前人研究的基础上，本文在以下几个方面对高速数据发送器进行了研究与实践。

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。

By auto regulating opening and closing of transmitter during speech or silence periods , discontinuous transmission DTx can reduce the interference , in return increases speech quality and saves power wasting , especially this technology is comported with large noise underground coal mine .

间断传输技术通过发射端有无话音信号自动调整发射机的开和关来达到减小系统干扰，提高通话质量和节省移动台功耗的目的，特别适用于干扰噪声大的煤矿井下通信。

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。

We assume that the total amount of transmitter released, rather than the frequency of release, mediates synaptic competition.

我们假设介导突触竞争的是，释放的传送物总数，而非释放频率。

Since the multiuser interferecnce is precancelled at the transmitter, each terminal user just utilizes the simple linear decoding to obtain the transmitted symbols.

由于多用户干扰在基站端被预去除，所以终端用户仅利用简单的线性解码即可获得发射符号。

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
