1.As such,every new version of the product requires a redesign and trips through the foundry,an expensive proposition,and an impediment to rapid time-to-market.

1.而且，每次推出一个新产品都需要重新设计并经历所有制造流程。这样做不但造价昂贵，而且不利于迅速上市。

2.Furthermore,we shall prove that a minimum theoretical sampling frequency of order 6.8 kilohertz(kHz)is required to convey a voice channel occupying the range 300 Hz to 3.4 kHz.

2.而且我们将证明，为了变换频率范围为300Hz~3.4kHz的话路信号，理论上的最小采样频率为6.8kHz。

3.For example,the signal received from a satellite,located in far outer space,is very weak and is at a level only slightly above that of the noise.

3.例如，从位于遥远太空中的卫星接收到的信号极其微弱，其电平仅比噪声稍高一点。

4.However,for applications in which the end product must process answers in real time,or must do so while powered by consumer batteries,GPPs comparatively poor real time performance and high power consumption all but rules them out.

4.然而，在最终产品必须实时响应的应用中，或者必须在电池供电下实现实时响应的应用中，由于GPP实时性能较差、功耗大、因此就被排除在外了。

5.Integration circuits are also classified according to their functions.Digital or logical IC are used as switches,they are either on or off.In computers the on and off states correspond to 0 or 1.Other IC is called linear or analog IC.

5.也可根据其功能不同对集成电路进行分类。数字IC（也称为逻辑IC）通常用作开关，表示接通或关断。在计算机中，接通和关断状态分别对应“0”或“1”。另一种IC被称为线性或模拟IC。

6.In addition,the signal processor may also add parity bits to the digital word to provide channel coding so that error detection and correction can be used by the signal processor in the receiver to reduce or eliminate bit errors that are caused by noise in the channel.

6.此外，信号处理器还可以给数码字加入奇偶校验位，即提供信道编码，使得接收机的信号处理器可以进行误码检测和纠错，以减少或消除由信道噪声所引起的误码。
