The fourth chapter discusses modulated filter banks . the theory and design method of prototype filter are provided 第四章討論了調(diào)制式濾波器組,給出余弦調(diào)制濾波器組的基本原理及設(shè)計方法。
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。
By using the lagrange multiplier approach , the design procedure is formulated as solving the linear equation iteratively to obtain the desirable prototype filter coefficient vector 使用拉格朗日乘數(shù)方法,算法通過迭代求解線性方程來獲得期望的原型濾波器系數(shù)矢量。
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.
