It is simply a set of flip-flops (usually D latches or RS flip-flops) connected together so that the output of one becomes the input of the next, and so on in series.1它就是一组触发器（通常是D锁存器或RS触发器）联在一起，使其中一个触发器的输出成为下一个的输入，依此形成一串。

On the leading edge of the next clock pulse, the contents of the first flip-flop is stored in the second flip-flop, and the signal which is present at the DATA input is stored in the first flip-flop, etc.在下一个时钟脉冲的前沿，第一个触发器的内容被存放到第二个触发器中，而在数据输入端的信号则存放在第一个触发器中，依此类推。

Roughly speaking, the transistor can be likened to an electronically controlled valve whereby energy applied to one connection of the valve enables energy to flow between two other connections.粗略地说，晶体管好似一种电子控制阀，由此加在阀一端的能量可以使能量在另外两个连接端之间流动。

It is called N-channel, because the gate voltage induces an N-channel within the substrate, enabling current to flow between the N-regions.因为栅极电压诱导基底上的N通道，使电流能在两个N区域之间流动。

This testing demonstrates that the device will function correctly over all extremes of the process, voltage and temperature.这一测试表明器件将在所有极端的过程、电压、温度下正常工作。

Conversely, unless the noise exceeds a certain threshold, the information contained in digital signals will remain intact.相反，只要噪声不超过一定的阈值，数字信号中的信息是不会丢失的。

Each mobile receives and transmits information from and to the base station via two RF channels called the “forward channel”or “downlink”and the “reverse channel”or “uplink,”respectively.每个移动单元通过两个射频信道接收来自基站的信息并向基站发射信息，这两个信道分别称为前向信道或下行链路，以及逆向信道或上行链路。

Sampling theorem states that the sampling frequency must be greater from twice the bandwidth of the signal采样定理指出采样频率必须大于信号带宽的两倍。

Not all of these terms will be relevant,but it is useful to remember that it is better to consider them initially rather than to be forced into retrospective modifications.汉译英所有参数可以大范围变化All parameters are subject to wide variations不要忽略这样一个事实。

有多少次是在用典型值设计好电路后发现（该电路）只是因为使用的器件不典型而不能工作？这就提出一个棘手的问题：在设计中何时应该使用典型值，何时应该使用最不利值？这是经验丰富的设计人员也必须进行的判断。

显然，如果某些性能要求是强制性的，则一定要用最不利情况下的数值。

然而在许多情况下某一规定性能是否可以取得将在易实现性，重要性，经济性之间取得折中。

Never forget this fact.How many times has a circuit been designed using typical values,only to find that the circuit does not work because the device used is not typical?The above statement thus poses a tricky question:when should typical values and when should worst-case values be used in the design?This is where the judgment of the experienced designer must be brought to bear.Clearly,if certain performance requirements are mandatory,then worst-case values must be used.In many cases,however,the desirability of a certain defined performance will be a compromise between ease of implementation,degree of importance,and economic considerations.。
