1.“信道”這個術(shù)語通常是指頻分多址系統(tǒng)中的一個頻率，時分多址系統(tǒng)中的一個時隙，碼分多址系統(tǒng)中的一個代碼或混合系統(tǒng)中的頻率，時隙，代碼中的某中組合。

The generic term channel is normally used to denote a frequency in FDMA system,a time slot in TDMA system,and a code in CDMA system or a combination of these in a mixed system.2.第三代系統(tǒng)的目的在于為用戶提供一個支持語音，數(shù)據(jù)，多媒體和視頻服務(wù)的無隙網(wǎng)絡(luò)，而不論用戶在網(wǎng)絡(luò)中的什么位置。

The third-generation systems aim to provide a seamless network that can provide users voice,data，multimedia,and video services regardless of their location on the network.3.邏輯綜合是將電子線路的高級描述轉(zhuǎn)換為一張邏輯門極其互連列表(即“網(wǎng)表”)的過程。邏輯綜合程序都能理解Verilog和VHDL的某個子集。

Logic synthesis is the conversion of a high-level electronic circuit description into a list of logic gates and their interconnections,called the “netlis”.Every logic synthesis program understands some subset of Verilog and VHDL.4.“復雜可編程邏輯器件”是一種在邏輯模塊之間具有可編程互連的可編程邏輯器件。多數(shù)復雜可編程邏輯器件是基于電可擦寫可編程只讀存儲器和閃存的。

CPLD(Complex PLD)is a programmable logic device that includes a reprogrammable interconnect between the logic blocks.CPLDs are mostly EEPROM and flash based.1

5.數(shù)字信號處理器(DSP)是無數(shù)家用和商用系統(tǒng)的關(guān)鍵部分，其應用領(lǐng)域與日俱增。因此，DSP正在成為技術(shù)專家和工程師專業(yè)知識的重要組成部分之一。

Digital signal processing is an essential element of countless home and business systems.Its domain can only increase as time proceeds.Thus, DSP is becoming an essential area of expertise for technologists and engineers.6.信號(如聲音，光和電壓)是攜帶信息的變化。模擬信號是現(xiàn)實世界中的信號。模擬信號在每個時間點上都有定義，其幅度的取值是無限的。

Signals ,like sound,light,or voltage,are information-bearing variations.Analog signals are real-world signals.They are defined at every point in time and may take an infinite number of possible amplitudes.英譯漢句子

1.Using better compression algorithms, it is possible to get the speech down to 4kbps , in which case six users can be stuffed into a frame, as illustrated in Figure 11.(b).From the operator's perspective , being able to squeeze three to six times as many D-AMPS user is a huge win and explains much of the popularity of PCS.如果使用更好的壓縮算法，還可以把語音數(shù)據(jù)率降至4kbps；這樣的話，一幀就可以容納6位用戶了。在運營商看來，“3—6位D—AMPS用戶只需占用相當于1位AMPS用戶所需的帶寬”是巨大的成功，而且在很大程度上解釋了“個人通信業(yè)務(wù)”（PCS,Personal Communication Service）普及的原因。

2.CDMA is completely different from AMPS ,D-AMPS, and GSM.Instead of dividing the allowed frequency range into a few hundred narrow channels, CDMA allows each station to transmit over the entire frequency spectrum all the time.Multiple simultaneous transmissions are separated using coding theory.CDMA also relaxes the assumption that colliding frames are totally garbled.Instead , it assumes that multiple signals add linearly.CDMA和AMPS、D—AMPS及GSM完全不同。CDMA沒有將可用頻帶分割為幾百個窄帶信道，而是允許信號在整個頻譜范圍內(nèi)傳送。利用編碼原理，CDMA可以將多個同時傳送的信號分離開來。在CDMA中，“相遇數(shù)據(jù)幀會造成數(shù)據(jù)混淆”的想法不存在了——CDMA認為多路信號之間是線性相加的。3.Motherboard-This is the main circuit board that all of the other internal components connect to.The CPU and memory are usually on the motherboard.Other systems may be found directly on the motherboard or connected to it through a secondary connection.For example , a sound card can be built into the motherboard or connected through PCI.主板：所有其他內(nèi)部組件都和主板連接。通常，CPU和內(nèi)部都位于主板上。其他組件可能直接位于主板上，也可能通過某種方式連接到主板上。例如，聲卡可以置于主板上，也可以通過PCI總線連接到主板上。

4.In practical terms , this means that one or two layers of metal interconnect must be designed.Since an integrated circuit requires seven or more processing stages , all the processing steps other than the final metalization can be completed in advance.Because the uncommitted gate arrays can be produced in volume ,the cost of each device is relatively small.從實現(xiàn)角度看，就是要設(shè)計一層或兩層的金屬互連線。集成電路的制造流程分為七個步驟（或更多），除去最后一步“金屬化”(metallization)之外，其他步驟都可以提前完成。由于門陣列可以大量生產(chǎn)，所以單個器件成本就比較低。

5.Physical layer communications : FPGAs have long used to implement the glue logic that interfaces between physical layer communication chips and high-level networking protocol layers.The fact that today's high-end FPGAs can contain multiple high-speed transceivers means that communications and networking functions can be consolidated into a single device.物理層通信：長久以來，F(xiàn)PGA用于實現(xiàn)通信芯片和高級網(wǎng)絡(luò)協(xié)議之間的“膠連”邏輯。實際上，今 2

天的高端FPGA可以容納多個高速無線收發(fā)器——即可將通信和網(wǎng)絡(luò)功能固化于單個器件中。

6.One of the most important applications of VHDL is to capture the performance specification for a circuit , in the form of what is commonly referred to as a test bench.Test benches are VHDL descriptions of circuit stimuli and corresponding expected outputs that verify the behavior of a circuit over time.Test benches should be an integral part of any VHDL project and should be created in tandem with other descriptions of the circuit.VHDL最重要的應用之一是以所謂“測試平臺”（test bench）的形式記錄電路的性能指標?！皽y試平臺”是驗證電路時域行為的激勵源及相應期望輸出的VHDL描述。在VHDL工程項目中，“測試平臺”是必不可少的，應該和其他電路描述一同創(chuàng)建。

7.A digital signal is a numerical representation of the analog signal.It may be easier and cost effective to process these signals in the digital world.In the real world ,we can convert these signals into digital signals through the analog-to-digital converter ,process the signals,and if needed ,bring the signals back out to the analog world through the digital-to-analog converter.數(shù)字信號是模擬信號的數(shù)值表示。在數(shù)字世界里，對這些信號進行處理可能會更容易、成本更低。在現(xiàn)實世界中我們可以通過“模數(shù)轉(zhuǎn)換”將信號轉(zhuǎn)換為數(shù)字信號，然后對信號進行處理；如果需要的話，用“數(shù)模轉(zhuǎn)換器”將信號轉(zhuǎn)換回到模擬世界中去。

8.Keep in mind that the distinction between DSPs and other microprocessors is not always a clear line.For instance ,look at how Intel describes the MMX technology addition to its Pentium processor : “Intel engineers have added 57 powerful new instructions specifically designed to manipulate and process video，audio and graphical data efficiently.These instructions are oriented to the highly parallel , repetitive sequences often found in multimedia operations.”

別忘了:DSPs和其他微處理器的界限并不是很清晰。例如，讓我們看一看inte是如何描述其奔騰處理器新增的MMX技術(shù)的：“為了高效操作和處理視頻、音頻和圖形數(shù)據(jù)，intel工程師新增了57條功能強大的指令。這些指令面向的是多媒體操作中經(jīng)常出現(xiàn)的、高度并行和重復的程序?！?/p>

9.In practical application , these are certainly many other factors to consider when evaluating analog versus digital filters ,or analog versus digital signal processing in general.Most modern signal processing systems use a combination of analog and digital techniques in order to accomplish the desired function and take advantage of the best of both the analog and the digital world.在實際應用中，在評價模擬濾波器和數(shù)字濾波器（或模擬信號處理和數(shù)字信號處理）的時候，坑定還要考慮許多其他因素。為了實現(xiàn)期望的功能和充分利用兩種技術(shù)各自的優(yōu)勢，多數(shù)現(xiàn)代信號處理系統(tǒng)都采用了模擬技術(shù)和數(shù)字技術(shù)相結(jié)合的方式。

10.Audiophiles demand the utmost sound quality , and all that factors are treated as secondary.If you had to describe the mindest in the world , it would be : overkill.Rather than just matching the abilities of the human ear ,these systems are designed to exceed the limits of hearing.It's the only way to be sure that the reproduced music is pristine.Digital audio was brought to the world by the compact laser disc, or CD.This was a revolution in music;the sound quality of the CD system far exceeds older systems, such as records and tapes

高保真音響愛好者對聲音質(zhì)量的要求極高，所有其他因素都被視為次要的。假如要用一個詞來描述這種心理活動的話，那就是“過分”。高保真音響系統(tǒng)不是設(shè)計得剛好滿足人類的聽覺需求，而是超越了人類的聽覺極限，這是唯一能夠確保再現(xiàn)音樂無任何失真的辦法。CD帶給世人數(shù)字音頻的享受。這是音樂領(lǐng)域里的巨大變化，CD系統(tǒng)的音質(zhì)遠遠超過了傳統(tǒng)的唱片磁帶。

11.Then the sample are processed in groups of 1152(about 26 msec worth).Each group is first passed through 32 digital filters to get 32 frequency bands.At the same time the input is fed into a psychoacoustic model in order to determine the masked frequencies.Next each of the 32 frequency bands is further transformed to provide a finer spectral resolution.在這之后，樣本以1152(約26ms)為一組進行處理。每組樣本首先通過32個數(shù)字濾波器，從而得到32 3

個頻帶。同時，輸入信號進入心理聲學模型以決定被屏蔽的頻率。下一步，32頻帶中的每個頻帶中的每個頻率進一步變換得到更好的頻譜分辨率。

An ASIC(Application Specific Integrated Circuit)is a chip that is custom designed for a specific application rather than a general-purpose chip such as a microprocessor.The use of ASICs improves performance over general-purpose CPUs.Because ASIC are “hardwired” to do a specific job and do not incur the overhead of fetching and interpreting stored instructions.
