&nbsp;&nbsp;我大四了,和老师商量了一下,想设计一个数字万用表,看了fluke的表,真是佩服,那么优秀的产品。<br />&nbsp;&nbsp;请问各位前辈,哪里有这些国外名表的资料可以参考?我在fluke的网站上下了一个78型的维修手册,上面讲了一些简化电路,挺好的。或者哪里有什么像凯斯利&lt&ltLow&nbsp;level&nbsp;measurement&nbsp;book&gt&gt这样的文档?再活着什么资料可以借鉴?英文汉语都可以。我的基础还算可以,想看一些解决方案性质的东西。小弟先谢了。

要做毕设,自己拿ADC和MCU去整吧

要做产品,国内大把廉价数字表都是ASIC方案,IC内该搞定了都搞定了,照着手册抄就是,价钱低得你不能想象

多谢

&nbsp;多谢两位前辈指教。特别是tyw前辈,奉献这么多资料。<br />&nbsp;PS:我做的不是毕业设计,只是练着玩。毕设还得下学期。
