After analyzing the relationship between the subdividing error and the sinusoidal index  a low-pass digital filter which can make the moire signal satisfy the need of 1024 subdivision is designed. Considering with the fundamental frequency varies with the rotating speed of encoder  the tunable filter is adopted  whose cutoff frequency is calculated according to the coarse information of the encoder. The simulating results show that the proposed method can improve the sinusoidal index  especially at high rotating speed. At last  the compensating algorithm is implemented in the terminal of satellite optical communication  which needs high resolution. The experimental results show indicate that the developed method is feasible. 2011 IEEE.   Design of transmission of high-speed CCD driving signals (EI CONFERENCE) 会议论文  OAI收割 2011 International Conference on Mechatronic Science, Electric Engineering and Computer, MEC 2011, August 19, 2011 - August 22, 2011, Jilin, China 作者:  Zhang S. 收藏  |  浏览/下载：146/0  |  提交时间：2013/03/25 In order to overcome the distortion problem of CCD driving signals caused by signal transmission  the detail implementation of transmission of high-speed CCD driving signals based on transmission line theory is discussed. The CCD driving signals are critical to the CCD to produce high quality images. In high speed application these drivers will occupy more circuit board areas and can not be put very close to the CCD. So the driving signals must be transmitted. Because the CCD exhibits capacitive load  the driving signals distortion problem is much severe. Transmission line theory is used to analyze the problem. The method of source termination is adopted to avoid signal reflections. Meanwhile the characteristic impedance of the circuit board and the resistance of terminal resistor are designed small enough to decrease the rising and falling time of the driving signals. Experimental results show that there is no distortion of the high speed driving signals after transmission. 2011 IEEE.
