使用半導體激光器在弱反饋條件下的動力學理論,建立了線性調頻半導體激光器的自混頻干涉理論模型.基於該模型,分析了激光器振蕩頻率偏移與輸出功率變化特性.通過測量激光器輸出功率譜,可以得到激光器前端面與被測目標之間的距離In chapter 5, the complex envelop simulation block diagrams of fh transmitter and receiver are presented at first. then key techniques of simulation system are discussed, including frame processing structure, fh sequence generator, etc. finally, simulation models of fh transmitter, receiver and jammer are presented. the influence of frequency excursion on performance of multi - tone continuous wave jamming is analyzed
第五章首先設計了跳頻發信機成員和接收機成員的復包絡模擬框圖;其次討論了跳頻模擬系統實現的關鍵技術,包括幀處理結構、跳頻序列發生器等;最後給出了跳頻通信發信機、接收機以及干擾機成員的模擬模型,分析了頻率偏移對多頻連續波干擾性能的影響。The frequency of the slave laser is not locked to the master laser when the polarization direction of the injected laser is perpendicular to the polarization direction of the slave laser which is free - running. the slave laser frequency shifts toward low frequency because of thermal effect in the slave laser cavity induced by the injected laser
當注入光偏振方向與從激光器輸出光偏振方向垂直時,從激光器頻率不會被鎖定到主激光器頻率上,但由於外部光注入引起的從激光器腔內熱效應,使得從激光器頻率向低頻方向移動。In this paper, an optimized design method is presented to deal with the edge field effect problem in the parallel - coupled microstrip bandpass filters
摘要提出一種通過提升設計頻率來解決平行耦合微帶帶通濾波器中邊緣場效應導致的中心頻率偏移的方法。The main works are organized as follows : based on the switching function method and time domain simulations, the small disturbance transfer a characteristic through the converter is analyzed. because of the modulation effect of the converter, the small disturbance in the shaft of turbine generator will induce ac voltage component with the same frequency as the disturbance on the dc side. and the resulted ac current on the dc side will have the similar frequency shift when transfers to the stator of the generator
主要內容包括: ( 1 )基於開關函數法和模擬分析,研究了機組轉子上次同步頻率的小擾動,在hvdc交直流兩側響應的頻率特性- - - -轉子上的小擾動經直流換流器調制后,將會在系統直流側感應出與擾動同頻率的電壓分量;直流側電流擾動反映到交流定子側,也將發生頻率偏移。To reduce the frequency of updates, we can send an update only when the original path and the replicated path diverge by a defined amount ( figure 1 ) ( it may then be necessary to run both the master entity and the replicate by the master process to compare them )
為了降低更新的頻率,我們可以只在原始路徑和復制體的移動路徑發生指定數量的偏離時才發送更新包(這可能需要在主處理器上同時運行主實體和其復制體的運動模擬,以用來對這兩條路徑進行比較) 。分享友人
