信號(hào)的調(diào)制及解調(diào),使系統(tǒng)簡(jiǎn)單,并要調(diào)制解調(diào)過程容易實(shí)現(xiàn),能正確的完成調(diào)制解調(diào)任務(wù)。system view是一種電子仿真工具。2FSK 調(diào)制系統(tǒng)System View is based on the modulation system 2FSKSummary: Modern munication systems require munication distance, large munication capacity, better transmission quality. As one of the key technologies demodulation technology it has been an important direction for researchers. From the earliest maturing AM FM analog technology, now widely used in digital modulation techniques. So that the transmission of information more efficient and reliable. Binary digital amplitude shift keying modulation is an old model, which is the basis of a variety of digital modulation. The course design is the use of System View simulation software platform to design a FSK modem system, using an oscilloscope modulated signal waveform before and after, and recorded, analyzed the performance of the system. System View simulation functional simulation of the actual FSK demodulation. This course is designed to study the FSK demodulation system based on System View. In this paper two methods demodulated brief introduction, and then pare the selected appropriate method to plete the design.Keywords: System View 2FSK Modulation system 目 錄前言 11 課程設(shè)計(jì)的任務(wù)與要求 1 課程設(shè)計(jì)的任務(wù) 1 課程設(shè)計(jì)的要求 1 課程設(shè)計(jì)的研究基礎(chǔ) 12 FSK調(diào)制解調(diào)的方案 2 2FSK調(diào)制的方案 2 模擬調(diào)頻法 2 鍵控法鍵控法 2 2FSK解調(diào)方案 3 非相干解調(diào) 3 相干解調(diào) 4 2FSK數(shù)字系統(tǒng)解調(diào)原理 43 System View的應(yīng)用 5 System View簡(jiǎn)介 5 System View的操作步驟 5 選擇設(shè)置信號(hào)源(Source) 5 選擇設(shè)置分析窗(Sink) 6 系統(tǒng)定時(shí)(System Time) 6 System View的用戶環(huán)境 6 System View的基本使用 7 System View的系統(tǒng)定時(shí)窗口 74 基于System View的仿真 8 2FSK調(diào)制 8 調(diào)制原理圖 8 解調(diào)原理圖 9 2FSK調(diào)制解調(diào)模型 9 2FSK的調(diào)制電路仿真 15 調(diào)制電路仿真 15 解調(diào)電路仿真 175 結(jié)束語(yǔ) 22參考文獻(xiàn) 2424基于System View的2FSK的調(diào)制系統(tǒng)設(shè)計(jì)前言當(dāng)今社會(huì)通信技術(shù)的發(fā)展速度可謂日新月異,計(jì)算機(jī)的出現(xiàn)在現(xiàn)代通信技術(shù)的各種媒體中占有獨(dú)特的地位,計(jì)算機(jī)在當(dāng)今社會(huì)的眾多領(lǐng)域里不僅為各種信息處理設(shè)備被使用,而且它與通信向結(jié)合,使電信業(yè)務(wù)更加豐富。本課程設(shè)計(jì)研究的是基于System本課程設(shè)計(jì)主要是利用System作為其關(guān)鍵技術(shù)之一的解調(diào)技術(shù)一直是人們研究的一個(gè)重要方向。2.了解2FSK的調(diào)制解調(diào)基本概念。xxxxxxxxxxxxx廣播電視方向課程設(shè)計(jì)基于System View的2FSK的調(diào)制系統(tǒng)設(shè)計(jì) 學(xué)生姓名學(xué) 號(hào)所在學(xué)院專業(yè)名稱班 級(jí)指導(dǎo)教師成 績(jī) Xxxxxxxxxxxxxxx二○一五年五月xxxxxxxxxxxxxxxxxxxx課程設(shè)計(jì)報(bào)告課程設(shè)計(jì)任務(wù)書學(xué)生姓名學(xué)生學(xué)號(hào)學(xué)生專業(yè)學(xué)生班級(jí)指導(dǎo)教師職 稱發(fā)題日期 2015年4月1日
