Specifying the right reference and applying it correctly isa more difficult task than one might first surmise, consideringthat references are only 2- or 3-terminal devices.Although the word “accuracy” is most often spoken inreference to references, it is dangerous to use this wordtoo freely because it can mean different things to differentpeople. Even more perplexing is the fact that a referenceclassified as a dog in one application is a panacea inanother. This application note will familiarize the readerwith the various aspects of reference “accuracy” andpresent some tips on extracting maximum performancefrom any reference.

Frequently, voltage reference stability and noise defi nemeasurement limits in instrumentation systems. In particular,reference noise often sets stable resolution limits.Reference voltages have decreased with the continuingdrop in system power supply voltages, making referencenoise increasingly important. The compressed signalprocessing range mandates a commensurate reductionin reference noise to maintain resolution. Noise ultimatelytranslates into quantization uncertainty in A to D converters,introducing jitter in applications such as scales, inertialnavigation systems, infrared thermography, DVMs andmedical imaging apparatus. A new low voltage reference,the LTC6655, has only 0.3ppm (775nV) noise at 2.5VOUT.Figure 1 lists salient specifi cations in tabular form. Accuracyand temperature coeffi cient are characteristic ofhigh grade, low voltage references. 0.1Hz to 10Hz noise,particularly noteworthy, is unequalled by any low voltageelectronic reference.

BeanShell是一個(gè)小型的，免費(fèi)的，可嵌入式的，具有面向?qū)ο竽_本語(yǔ)言特性的Java代碼解釋器。它是用Java語(yǔ)言寫(xiě)的。它能執(zhí)行標(biāo)準(zhǔn)的Java語(yǔ)句和表達(dá)式，還自帶簡(jiǎn)單的腳本命令和語(yǔ)法。它把編程對(duì)象當(dāng)成一個(gè)簡(jiǎn)單的方法，這很像Perl和JavaScript.
你可以在寫(xiě)Java測(cè)試或調(diào)試時(shí)使用BeanShell，也可以用它作為你的應(yīng)用程序的腳本引摯。簡(jiǎn)而言之，BeanShell可以動(dòng)態(tài)的解釋JAVA語(yǔ)言。也就是說(shuō)BeanShell在許多方面對(duì)于Java的用處就像Tcl/Tk對(duì)于C的用處一樣：BeanShell是可嵌入式的---你可以在運(yùn)行時(shí)從你的應(yīng)用程序調(diào)用BeanShell去動(dòng)態(tài)的執(zhí)行Java代碼或是為你的應(yīng)用程序提供腳本擴(kuò)展。相反，你也可以從BeanShell調(diào)用你的應(yīng)用程序及其對(duì)象，它可以讓JAVA對(duì)象和API動(dòng)態(tài)運(yùn)行。正因?yàn)锽eanShell是用JAVA寫(xiě)的，所以它可以和你的應(yīng)用程序運(yùn)行在同一個(gè)JVM空間內(nèi)，你也可以自由的傳遞實(shí)時(shí)對(duì)象的參照(references)到腳本代碼中并且作為結(jié)果返回。

詞法分析器制作與應(yīng)用
設(shè)計(jì)思想
(1)程序主體結(jié)構(gòu)部分：
說(shuō)明部分
％％
規(guī)則部分
％％
輔助程序部分
（2）主體結(jié)構(gòu)的說(shuō)明
在這里說(shuō)明部分告訴我們使用的LETTER,DIGIT, IDENT(標(biāo)識(shí)符,通常定義為字母開(kāi)頭的字母數(shù)字串)和STR(字符串常量,通常定義為雙引號(hào)括起來(lái)的一串字符)是什么意思.這部分也可以包含一些初始化代碼.例如用#include來(lái)使用標(biāo)準(zhǔn)的頭文件和前向說(shuō)明(forward ，references).這些代碼應(yīng)該再標(biāo)記"％{"和"％}"之間 規(guī)則部分> 可以包括任何你想用來(lái)分析的代碼 我們這里包括了忽略所有注釋中字符的功能,傳送ID名稱(chēng)和字符串常量?jī)?nèi)容到主調(diào)函數(shù)和main函數(shù)的功能.
（3）實(shí)現(xiàn)原理
程序中先判斷這個(gè)句語(yǔ)句中每個(gè)單元為關(guān)鍵字、常數(shù)、運(yùn)算符、界符，對(duì)與不同的單詞符號(hào)給出不同編碼形式的編碼，用以區(qū)分之。
PL/0語(yǔ)言的EBNF表示
<常量定義>：：=<標(biāo)識(shí)符>=<無(wú)符號(hào)整數(shù)>
<標(biāo)識(shí)符>：：=<字母>={<字母>|<數(shù)字>}
<加法運(yùn)算符>::=+|-
<乘法運(yùn)算符>::=*|/
<關(guān)系運(yùn)算符>::==|#|<|<=|>|>=
