| 摘 要： | 提出了一种新颖的电阻网络设计方法，该方法设计误差小、音量调节精度高、版图容易实现。该设计方法是在串联电阻网络的基础上进行了改进，提出了串并联电阻网络结构，误差降到0．6％以内。实现了串联电阻网络无法实现的大衰减，可达99dB，调节步进为1dB．

| Abstract: | The design of resistance network is presented The method has the advantage of little deviation, high precisions of volume adjusting and easy realization of the domain. This method improves the original model which based on the series resistors net, and proposes novel series-parallel resistors net. It also makes the attenuation become true successfully. Experiments result shows that the maximum error is only 0. 6%, so it has reached a good accuracy. Attenuation ldB/Step in the range of 0 dB-99 dB. |
