中文拼音 [shǎidùxìnháodàikuān]
色度信號帶寬
英文
chromaticity bandwidth-
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。Also, much related research requires the narrowband assumption, which is not always realistic in practical applications. it is necessary to analyze the effects of finite bandwidth to bearing estimation of spatially distributed source. additionally, more complex noise models should be dealt with in practical situations as well as that of white gaussian noise
不過，其中多數方法僅適用於小角度擴展情況，當角度擴展比較大時，需要在估計的穩健性和運算量之間進行折中；而且，許多方法要求信號傳播滿足窄帶假設，這在實際的應用場合中可能很難得到滿足，有必要分析信號帶寬對分佈源波達方向估計的影響；另外，也有必要考慮空間色噪聲環境中的分佈源波達方向估計問題。
