【正文】 teus 濱州學院本科畢業(yè)設計（論文 ） II Design And Realization About The Simulation Case Of A/D And D/A Abstract In the modern digital society, digital voltage meter testing is often used, will detect the data into the puter system, plete the putation, storage and analog signal data digital signal data into our familiar. Circuit design, simulation is very important, the simulation provides a great help for the circuit design, we are easy to modify, improve the efficiency of design. Using AT89C51 microcontroller in A/D converter ADC0809, D/A converter DAC0832 as the main ponents of Proteus simulation, simulation design of analog digital analog conversion. Key words： Singlechip； A/D,D/A convert； Proteus； ADC0809； DAC0832 濱州學院本科畢業(yè)設計（論文 ） i 目 錄 第一章 緒論 ....................................................................................................................... 1 研究的目的和意義 .................................................................................................... 1 研究目的 ............................................................................................................. 1 研究意義 ............................................................................................................. 1 第二章 國內外現狀 和切入點 ........................................................................................... 2 國內外研究現狀 ........................................................................................................ 2 國外研究現狀 ..................................................................................................... 2 國內研究現狀 ..................................................................................................... 3 .............................................................................................................3 第三章 模數數模轉換元器件 介紹 ................................................................................... 4 模數數模轉換主要元器件介紹 ................................................................................ 4 模數數模轉換 主要 元器件概述 ......................................................................... 4 第四章 數模模數轉換主要功能設計與 實現 ....................................................................8 數模轉換 主要功能 設計與實現 ................................................................................ 8 單極性數模仿真案例功能設 ............................................................................. 8 雙極性數模仿真案例功能設計 .........................................................................11 模數轉換主要功能設計與實現 .............................................................................. 14 LED 顯示模數轉換功能設計 ............................................................................14 LCD顯示模數轉換功能設計 ............................................................................17 數模轉換綜合應用設計與實現 .......................................................................20 .............................................................................20 第五章 數模模數仿真 測試 及結果 ..................................................................................23 模擬仿真 測試 ...........................................................................................23 濱州學院本科畢業(yè)設計（論文 ） ii 真結果測試 ........................................................................................23 ....................................................................................23 ....................................................................................24 ...........................................................................................24 LED顯示仿真結果測試 ...................................................................................24 LCD顯示仿真結果測試 ...................................................................................25 ...................................................................................25 ....................................................................................25 結論 .....................................................
