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，每次推出一個新產(chǎn)品都需要重新設(shè)計并經(jīng)歷所有制造流程。這樣做不但造價昂貴，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.而且我們將證明，為了變換頻率范圍為300Hz~3.4kHz的話路信號，理論上的最小采樣頻率為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，從位于遙遠太空中的衛(wèi)星接收到的信號極其微弱，其電平僅比噪聲稍高一點。

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，在最終產(chǎn)品必須實時響應(yīng)的應(yīng)用中，或者必須在電池供電下實現(xiàn)實時響應(yīng)的應(yīng)用中，由于GPP實時性能較差、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.也可根據(jù)其功能不同對集成電路進行分類。數(shù)字IC（也稱為邏輯IC）通常用作開關(guān)，表示接通或關(guān)斷。在計算機中，接通和關(guān)斷狀態(tài)分別對應(yīng)“0”或“1”。另一種IC被稱為線性或模擬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，信號處理器還可以給數(shù)碼字加入奇偶校驗位，即提供信道編碼，使得接收機的信號處理器可以進行誤碼檢測和糾錯，以減少或消除由信道噪聲所引起的誤碼。
