A scheme of designing audio auto gain control system based on tda7315 is introduced , the diagram of chip matching as well as the software flowing chart are also given 摘要詳細闡述了一種以芯片tda7315設計的音頻增益控制系統設計方案,同時提供芯片連接關系示意圖及軟件算法流程圖。
Because of the serial structure , it makes an emulational experiment about the frequency of sampling , coding and its bit . with the technique of agc ( auto gain control ) , the system solves the question about overflow when several persons are speaking at the same time 然后,本文研究了對模擬信號處理中的抗混疊濾波和采樣等技術,并針對本系統的串行特性,對編碼方式和量化位數進行分析和仿真。
In this paper , it gives the mechanism of charge - coupled devices and its plane borehole pattern , and show how the digital camera work . 2 . it studies the reconstruction algorithm for digital camera . the theory of color is firstly introduced , then algorithm are studied in this paper , these algorithm are subtracting of fix - pattern noise , color reconstruction auto gain control algorithm and auto white balance algorithm , then designed a download soft for digital camera 首先對顏色理論作了簡單的介紹,然后根據數碼相機的工作過程對各階段所用的圖像處理算法進行了研究,這些算法包括固定圖案噪聲的去除算法、自增益控制算法、白平衡調整算法、顏色重建算法以及灰度拉伸算法,最后利用這些算法開發了一個數碼相機的下載軟件。
