二十一世紀的今天，是個欣賞方式由讀寫時代向讀圖時代邁進的嶄新時代，攝影記者身肩重任，能否繼續擔當新聞采編隊伍的主體，而不是配角，使他們用相機捕捉下了稍縱即逝的場面，從而記錄下歷史的變革，通過視覺形象使我們能夠完整地感受生活，這就需要攝影記者跳出舊框框，涉及到「數字化」 ，人文關懷、平民視角、策劃理念等方面的觀念轉變，時刻保持清醒的頭腦，居危思安，奮發學習，勇於創新，才可能超越別人，超越自己，推陳出新，在百舸爭流的傳媒競爭中拍出更多更好的無愧於時代的新聞攝影佳作。The video signal processing circuit realizes the primary catching, filtering and signal amplifying. variable threshold binarization processing circuit and two - channel counter are designed to sample to count the output pulse signal, which is processed, deposited and displayed in microprocessor. the communication interface circuit with the computer is also designed
視頻信號處理電路完成了原始信號的初級捕捉、濾波、視頻放大等處理，設計了浮動閾值二值化處理電路，採用兩路計數器對輸出脈沖信號采樣計數，最後送入微處理器進行運算處理，可實現測量值的儲存、顯示等，並設計了與上位機的通訊介面。This dissertation adopts a universal digital ds / dmpsk modulation and demodulation scheme which is based on fpga. this scheme adopts quadrature balanceable modulation, intermediate frequency sampling, digital matched filtering, delay differential demodulation techniques and so on. it directly processes the digital signals on intermediate frequency without down - conversion, and doesn ’ t need pseudo random codes synchronization and carrier wave extraction circuits
本文採用了一種基於fpga的通用數字調制解調方案，該方案在調制端採用了正交平衡調制技術，在解調端採用了中頻帶通采樣、數字匹配濾波、延時差分解調等技術，直接在中頻上進行數字信號處理，不需要進行下變頻，也不需要增加額外的偽隨機碼同步捕獲和載波提取電路。
