使整個供暖系統具有正常情況下不需人工干預，有故障時可手動操作，各設備間聯鎖保護等功能。The principle and structure of pll ( phase - locked loop ), including fll and loop filter, are analyzed and described. the module of carrier synchronization in the all - digit ds - qpsk receiver was carried out in the fpga chip. the problem about the estimation and track of the correlative carrier frequency under high dynamic circumstances was resolved very well
針對某遙測遙控全數字接收機的研製，對相干載波同步中的鎖相環、鎖頻環、 dpll 、本地nco等進行了詳細的分析和優化設計，在fpga上實現了高動態全數字ds - qpsk接收機中的載波同步模塊，解決了大范圍和動態多普勒頻移下接收機的相干載波提取與跟蹤問題。Confronted with serious foreign intervention during the american civil war, lincoln administration made efforts to prevent england and france from admitting the southern confederacy, blockaded the import of materials into the southern confederacy, precluded england and france from manufacturing warships for the southern confederacy, and issued the emancipation proclamation in order to gain the sympathy of the world
摘要美國內戰期間，在面臨嚴重外來干涉的情況下，林肯政府力圖阻止英法列強承認南部同盟，對南部同盟進行封鎖，杜絕物資流入南方，並阻止英法為南部同盟製造軍艦，變相干涉美國內戰；為了獲得世界人民的同情，還頒布了《解放奴隸宣言》 。The simulation results show the method can attain our aim under harmonic condition. then the calculation errors have been analyzed
模擬結果表明，在有諧波干擾的情況下，數字鎖相環方法可以準確地跟蹤信號頻率的變化和計算相位差。39 % of total conversion efficiency at pump level of 600mw 858nm is obtained experimentaily with our single - resonant, external ring frequency - doubler pumped by tr. sapphite laser at room temperature ( about 21. 50c ). the conversion efficiency is seriously limited by what is called " blura " ( blue light induced infrared absorption ) and thermal effects. yet, up to 137 mw of cw blue light at 429nm at pump level of 565 mw has been achieved and stabilized over a hour when the cavity is locked via pound - drever - hall ( pdh ) technique
泵浦功率為600mw時，由於兩種效應「藍光導致紅外吸收（ bliira ） 」和「熱效應（ thermaleffects ） 」的嚴重影響，室溫下（約21 . 5 ）獲得了39的倍頻轉換效率；採用邊帶鎖頻技術， 565mw的泵浦光獲得137mw的藍光輸出，在沒有外界強烈的干擾下可以鎖定1小時以上而不失鎖。It is mainly appeared as the electromagnetic wave coupled into less shielded if cable, the if retransmit caused by the coupling between uplink and downlink in an earth station, and the frequency hopping or sweeping interference caused by an unlocked uplink frequency resource
其表現主要有，因中頻電纜屏蔽不佳而產生的串擾，因地球站上下行通道存在耦合而出現的中頻轉發，以及因上行設備頻率源失鎖而引致的跳頻或掃頻干擾。分享友人
