Modern communication system has been switched from analog signals transmission to digital signals transmission 在現(xiàn)代通信系統(tǒng)中,使用數(shù)字信號傳輸?shù)膬?yōu)勢越來越明顯。
Based on introduction of the isolated analog signal transmission , this paper made analysis and comparison of a variety of isolated technologies , and put forward a novel digital isolating method based on serial interface d / a converter 針對系統(tǒng)在不同模塊之間信號隔離傳輸?shù)膯栴},對各種模擬信號傳輸?shù)姆绞竭M行了性能比較,研究了模擬數(shù)字式變換傳輸?shù)姆绞降母鞣N應(yīng)用。
Based on scheme composing , i finished the designs and tailors of the virtual instrumentation hardware architecture ? the analog signal transmission circuits : the designs and simulations of signal processing card and data acquiring card , the tailors and debugging of their printing circuit cards 完成虛擬儀器硬件?模擬信號傳送電路的設(shè)計和制作:完成信號調(diào)理電路板和數(shù)據(jù)采集卡電路的設(shè)計和仿真,制作印制電路板,并調(diào)試完成,達到了設(shè)計要求。
With the rapid development of microelectronics , computer and communications , industrial control network has also constantly developed , from distributed control system ( dcs ) which based on analog signals transmission , fieldbus which is digital , intelligent and entirely disperse , to industrial ethernet which appeared and rapidly developed in recent years 隨著微電子技術(shù)、計算機技術(shù)以及通信技術(shù)的飛速發(fā)展,工業(yè)控制網(wǎng)絡(luò)也不斷向前發(fā)展,從基于模擬信號傳輸?shù)募⒖刂葡到y(tǒng)( dcs ) ,到數(shù)字化、智能化、全分散的現(xiàn)場總線,再到近年來新出現(xiàn)并得到迅速發(fā)展的工業(yè)以太網(wǎng)。
