As a mix - mode chip, the application - specific controller including analog signal and digital signal processing block can be applied to receiving, amplifying, processing, controlling signals of pir, and offer a wide application in some fields. in analog circuits, by sub - threshold mosfet, a self - bias current source is presented, which has a high power supply restrain ratio and a complementary to absolute temperature characters
這款晶元是一款數模混合晶元,包括模擬信號處理(含模數介面模塊)和數字信號處理兩大模塊,完整實現對紅外信號的接收、放大、處理、控制,產生有效數字電平驅動繼電器、可控硅等負載,應用於自動燈等多種場合。The second, at the high frequency primary coil, when switch turn on with control signal ( the spwm pulse is modulated ), in the positive or negative semi - period of low frequency modulation signal, transformer coil with same direction voltage. the magnetic flux of transformer core will increase step by step. at the end, it leads to magnetic flux saturation
二、在高頻變壓器原邊,當開關管接收控制信號脈沖列(經調制的spwm波列)導通時,在低頻調制信號的正半周或負半周內,施加在變壓器繞組上的是同一方向的電壓,變壓器磁芯中的磁通可能將級進地逐漸增加,導致磁芯飽和,造成磁偏或單向磁化,導致低頻電信號放大失真或由於很大的磁化電流而無法正常工作。To utilize the advantages of dsp chips, the system should be computing sources economical. according to digital signal processing theory, the poly - phase fir can help reduce the workloads of the ddc / duc. therefore, adding the complex carrier mixers, the channelization system ( a method of using a single wideband facility to transmit many relatively narrow - bandwidth signals. by subdividing the frequency spectrum used in the wideband channel ) can be formed utilizing the characters of fft
為了使開發出的軟體可以適用於高速dsp器件開發,節省系統資源,課題首先從數字信號處理的理論進行分析,得出可以利用抽樣率轉換的數字濾波器的特點,即多相濾波實現數字上下變頻計算負擔的減小,之後進一步將多相濾波器與頻譜搬移部分結合,通過公式的推導,得出可利用快速傅立葉變換的特點實現多路信號的通道化發射和接收的處理模型。The aimd has got a widely apply for its briefness and ease. at the other hand, it contain limited information because it has only two status : overload or under load. it cannot represent the true demand of the receiver and at the same time the policies of window adjust destroy the demand of smoothness of load, so it cannot afford the request of real - time streaming media
Aimd從演算法的簡單性和實際網路容易實現的角度考慮,反饋給發送方的信息有限,只有過載或欠載兩種二進制狀態; aimd演算法根據瓶頸資源的擁塞狀態向所有用戶發送相同的反饋信號,並不能真實反映接收節點對發送方負載量的要求;同時, aimd的窗口調整策略破壞了負載平滑性的要求,不能滿足當前實時流媒體應用, aimd的這些不足,體現了一種性能和系統復雜度之間的折衷。" i probably ( am ) overly offensive ( sensitive ) it ( to ) was ( the word ) lost. i did not feel they are lost. " this is richard n, a ( goddard ) space flight center engineer who is in charge of television process from all of nasa ' s ground receving sights
"我或許對丟失那詞很敏感.我不認為磁盤會丟了" r說.他是一名來自g航天中心的工程師,並負責對所有美國宇航局地面接收到的畫面進行電視信號處理First, the system converts the received tv program signals into mpeg file with video capture card, cut the mpeg file into several short mpeg files according to the content of the program and establish index for them. then, it transports the short mpeg files to jukebox server. the jukebox server with responsibility for discs management, it record the program material into discs and provide service for clients visit the program online
系統將接收到的衛星電視信號通過視頻採集卡,把它採集成mpeg文件,再根據節目內容將mpeg文件分段成小的節目素材文件並建立檢索索引,然後將它傳遞到光盤庫服務器;光盤庫服務器負責光盤的管理,它一方面將節目素材文件刻錄到光盤上,另一方面為客戶機提供在線訪問服務;客戶端根據一定檢索條件進行檢索,獲得所需的節目素材文件,並下載到本地,本地的媒體編輯軟體直接對mpeg文件進行編輯,生成新的節目。Also in this part, multi - thread programming and network communications are presented. in the visual system one thread process receives the control signal and the other take charge of the refreshing window. this technique solves the delay phenomenon between the visual system and the operations on the control panel
最後論文中對多線程編程進行了詳細分析,針對實時視景模擬系統的特點,使用一個線程完成控制信號的接收工作,另一個線程負責整個場景畫面的繪制工作。分享友人
