In our proposed method , both the objective function and the perfect reconstruction condition are expressed as a quadratic function of the prototype filter coefficient vector 該方法中,目標(biāo)函數(shù)和完全重構(gòu)條件均被表示成為原型濾波器系數(shù)矢量的二次函數(shù)形式。

百科解釋
Prototype filters are electronic filter designs that are used as a template to produce a modified filter design for a particular application. They are an example of a nondimensionalised design from which the desired filter can be scaled or transformed.
