This paper refers to several creation in compatibility with large volume of fed display and conversion of different video signal. it firstly used special central chip al300, designed correlative circuits, successfully developed vga full - color fed console system, compatible with resolution 1280 1024, achieved functions such as multi - video signal conversion and interleaving, met vga ’ s resolution of fed. it firstly designed and fabricated vga interface and separated video interface - - s - video, converting several video signals to 24 bits full - colored digital image signal in fed driving system, achieved separation of luminance signal and chromatism signal, enhanced the bandwidth of luminance signal
首次採用平板顯示專用控制晶元al300 ,設計並製作了相關配套電路,支持的最高解析度是1280 1024 ,實現解隔行和多種視頻格式轉換的功能,滿足了fed顯示屏對vga解析度的要求。首次在基於fpga的vga級彩色fed控制系統中設計並製作了vga介面和分離電視信號s - video介面,可以將多種視頻信號變換為fed驅動系統可用的24位彩色數字圖像信號,實現亮度信號和色差信號的分離,提高了亮度信號的帶寬。Again, small dc shifts in the black level caused by residual sync can disturb the color balance or gains of the video channels
同樣,由於殘留的同步信號而導致的黑電平上很小的直流偏移依然能夠影響顏色的平衡和各個視頻通道的增益。In this paper, the relative acknowledge of radar signal simulation system is introduced briefly, at first. then, a general platform is given which is referred to the software radio principle and made up with dsp and fpga
本文簡要介紹了雷達信號模擬系統的有關知識,並在軟體無線電思想的指導下設計了以dsp和fpga為核心的通用雷達視頻模擬平臺方案。And pays emphasis on analyzing the system structure and system flow, the core techniques, the channel characteristic and parameters of dvb - t system. the system adopts some core techniques such as cofdm, a lot of tps ( transmission parameter signalling ) insert and guard interval, and so on. so it can withstand high - level ( up to odb ), long delay static and dynamic multipath distortion
論文首先描述了數字電視地面廣播的需求條件,技術難點和目前存在的問題,並重點分析了dvb - t系統結構流程,核心技術及系統通道特性和參數,該系統採用了cofdm (編碼正交頻分多路復用) ,大量導頻信號插入和保護間隔技術等核心技術,使之能抵抗高電平( 0db ) ,長延時的靜態和動態多徑失真,有利於數字和模擬電視的混合傳輸,它的多載波調制模式功能和性能在移動和便攜接收、同頻網等方面具有獨特的優勢。Computer control system incepts two video signals, real - time disposes video, obtains undershoot values and relative distortion of vessel by combining two measurement results
計算機控制系統接收兩組光電自準直平行光管的視頻信號,進行實時圖像處理,得出動態脫靶量,並對兩路圖像的測量結果進行疊加得出艦艇的相對變形量。Addressable - able to signal from the headend or hub site in such a way that only the desired subscriber ' s receiving equipment is affected, making it possible to send a signal to a subscriber to change their level of service ( e. g. adding a new premium channel )
有選址功能的- -有選址功能的有線電視設備,能從有線電視設備前端或電線插孔發出節目信號,只有那些有需求的用戶的接受設備才能收到此信號,這就能做到向用戶發出信號來改變他們的服務水平,比如增加一個新的付費頻道等。For radar is a complicated electronic system, the implementation of uwb will be subject to the level of electronic hardware. the large instantaneous bandwidth of uwb return causes great trouble to receiver
由於雷達是綜合性很強的電子系統,超寬帶雷達的具體實現要受到實際硬體水平的限制,其中視頻回波信號瞬時大帶寬給接收機數據採集造成了很大的困難。分享友人
