站长，不好意思...
我将我的信箱写错了...
写成：ddccbbaa@sina.cn了...
前面我传输的文件是：“qibaoshanplan.doc”这个文件，并且，是我的一篇论文底稿，我还想您提出了建议“增加创意文案的文件上载”的类型。
我的名字叫：褚江。
这篇文建，我又重新上传了一下...
我会为我的错误买单，马上我再传一篇论文，是我在《云计算》的课堂上书写的...
希望站长，能够将弟我，重新添加到PUDN的大家庭中。

[系统设计方案] MT-001-SNR
接触ADC或DAC时您一定会碰到这个经常被引用的公式，用于计算转换器理论信噪比
(SNR)。与其盲目地相信表象，不如从根本上了解其来源，因为该公式蕴含着一些微妙之
处，如果不深入探究，可能导致对数据手册技术规格和转换器性能的误解。记住，该公式
代表的是完美N位ADC的理论性能。您可以比较ADC的实际SNR与理论SNR，看看二者有
何异同。
Contact ADC or DAC, you will encounter this oft-quoted formula used to calculate the theoretical signal-to-noise ratio (SNR) of the converter. Its blindly believe that the appearance, not as good as a fundamental understanding of its sources, because the formula contains some of the subtleties, if you do not go into details, could lead to a misunderstanding of the data sheet for technical specifications and performance of the converter. Remember, the formula represents the theoretical performance of a perfect N-bit ADC. You can compare the actual SNR with the theoretical SNR of the ADC, take a look at the similarities and differences between the two. (2013-03-17, PDF, 278KB, 下载11次)
