摘要
针对基于DSP的轴角编码器,运用叠加三角波理论提高A/D转换的分辨率。介绍叠加三角波理论,并结合基于DSP的轴角编码器,对三角波信号的参数设置进行研究,从而有效的提高A/D转换的分辨率。利用叠加三角波法加适当的外围电路,与外接高分辨率的ADC芯片相比,具有更高的性价比,较好的满足轴角编码器对A/D转换的需求。
According to rotary encoder based on DSP, this paper introduces an increasing resolution of A/D converter' method. Adding triangular signals and researching on the parameter setting of triangular signals, it can increase resolution of A/D converter. Compared with high-resolve ADC, this method has higher performance-price ration and can realize the A/D conversion in rotary encoder,
