perfect reconstruction condition

基本解釋

Meanwhile, by polyphase factorization, it was proved that the low-pass filter satisfies perfect reconstruction condition.
同時(shí)借助多相位分解，證明了多通道低通濾波器滿足完全重構(gòu)條件。
Firstly, the theory of multi-channel derivative sampling is described and the compact perfect reconstruction condition is given.
首先闡明了多階微分采樣的原理，給出了更為簡(jiǎn)潔的完美重構(gòu)條件。
The traditional method is that the impulse response of filter can be gotten by optimization under the perfect reconstruction condition. The performance of filters is not very good.
傳統(tǒng)的研究方法是在滿足濾波器組完全重構(gòu)的情況下通過尋優(yōu)的方法得到濾波器的沖擊響應(yīng)，所得到的濾波器性能較差。
