2、數(shù)字電路與模擬電路的共地處理

   現(xiàn)在有許?PCB不再是單一功能電路（數(shù)字或模擬電路），而是由數(shù)字電路和模擬電路混合構(gòu)成的。因此在布線時(shí)就需要考慮它們之間互相干擾問題，特別是地線上的噪音干擾。

   數(shù)字電路的頻率高，PCB鑼板機(jī)6，模擬電路的敏感度強(qiáng)，對(duì)信號(hào)線來說，高頻的信號(hào)線盡可能遠(yuǎn)離敏感的模擬電路器件，PCB鑼板機(jī)，對(duì)地線來說，整人PCB 對(duì)外界只有一個(gè)結(jié)點(diǎn)，所以必須在PCB內(nèi)部進(jìn)行處理數(shù)、模共地的問題，而在板內(nèi)部數(shù)字地和模擬地實(shí)際上是分開的它們之間互不相連，只是在PCB與外界連接的接口處（如插頭等）。數(shù)字地與模擬地有一點(diǎn)短接，請(qǐng)注意，PCB鑼板機(jī)5，只有一個(gè)連接點(diǎn)。也有在PCB上不共地的，這由系統(tǒng)設(shè)計(jì)來決定。

本專業(yè)課程設(shè)置的覆蓋面廣，所學(xué)的東西與其他學(xué)科交叉甚多。這也與本專業(yè)的來歷有關(guān)，自動(dòng)化專業(yè)大部分源于計(jì)算機(jī)或者電子工程系的自動(dòng)控制專業(yè)。

　　隨著我國經(jīng)濟(jì)的不斷發(fā)展，現(xiàn)代化工業(yè)的不斷發(fā)展使電氣自動(dòng)化技術(shù)方面的人才市場(chǎng)有著相當(dāng)大的潛力。尤其是廣東地區(qū)，自動(dòng)化生產(chǎn)技術(shù)不斷提高，自動(dòng)化產(chǎn)品不斷普及，智能樓宇和智能家居的應(yīng)用，智能交通的不斷發(fā)展，為電氣自動(dòng)化技術(shù)專業(yè)提供了廣闊的發(fā)展前景。瑞盛RASEM

Job prospects

One belongs to the information industry automation. Information industry was praised as 'sunrise industry'， the development of fast， will need more than talent， high treatment are the main trend of the development of science and technology today. Therefore，PCB鑼板機(jī)2， as an important part of the information industry， the automation also has a glorious future. The second is automation application range. At present， almost all industrial sectors can hang the bait， with automatic cool of the modernization of agriculture， national defense is closely related to automation. 3 it is to this professional very beneficial for personal development. This professional curriculum of coverage， and other disciplines cross very much what they have learned. This also related to the origin of this major， automation most stems from a computer or electronic engineering department of automatic cool.

With the continuous development of our couy's economy， the continuous development of modern industrial electrical automation technology talents market with considerable potential. Especially in guangdong region， automated production technology constantly improve， expansion of automation products of intelligent building and the application of smart home， the development of intelligent transportation for electrical automation technology professional provide a broad development prospects.
