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.   Speech signal enhancement through wavelet domain MMSE filtering (EI CONFERENCE) 会议论文  OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China Fenghua Z.; Le Y.; Jian W.; Qiang S. 收藏  |  浏览/下载：24/0  |  提交时间：2013/03/25 A new speech enhancement system that combine robust signal enhancement and minimum signal distortion is proposed in this paper. The proposed method introduces frequency depended  parametric  MMSE filtering techniques that involve wavelet packets. Voice activity detection (VAD) is used to further distinguish speech from noise and help to adaptively remove noise components from color noise eruptive noisy speech  while perceptual criteria is also taken into account. Experimental results and objective quality measurement test results validate the proposed speech enhancement system and illustrate the benefit of the proposed wavelet domain MMSE filtering as an excellent speech enhancement method to provide sufficient noise reduction and good intelligibility and perceptual quality  without causing considerable signal distortion and musical background noise method. 2010 IEEE.   Delta-sigma modulation for direct digital frequency synthesis 期刊论文  iSwitch采集 Ieee transactions on very large scale integration (vlsi) systems, 2009, 卷号: 17, 期号: 6, 页码: 793-802 作者:  Yang, Dayu;  Dai, Fa Foster;  Ni, Weining;  Yin, Shi;  Jaeger, Richard C. 收藏  |  浏览/下载：37/0  |  提交时间：2019/05/12 Cmos  Digital frequency synthesis (dds)  Frequency synthesis  Noise shaping  Signal to noise and distortion ratio (sinad)  Spurious free dynamic range (sfdr)  Delta sigma modulation
