1·The factors which will be encountered are descried and modules include anti-aliasing filter, clock circuit, band gap voltage reference, sc integrator, latched comparator and DAC are designed.

最后在考虑实际因素的基础上，依次设计了时钟产生电路、前置滤波器、带隙基准源、开关电容积分器、锁存比较器和DAC等子模块电路并做了仿真。

2·In an extreme case, when the aliasing effects are very severe, using wiener filter can reduce the prediction errors'energy by about 50% in comparison with using the ideal low pass filter.

极限情况下，当混叠十分严重时，相对于理想低通滤波器，用维纳滤波器进行亚象素插值能将预测残差均方和减少一半。
