prototype filter

基本解釋

Using these formulae, we can, directly, optimize the prototype filter coefficients in a quadratic form.
利用這些公式，我們可以以二次型形式直接優(yōu)化原型濾波器系數(shù)。
This thesis mainly designs the efficient prototype filter and modulation filter set using the method of Frequency-Response Masking(FRM) and simulates them using MATLAB software.
本課題主要是利用頻罩法實(shí)現(xiàn)高傚的原型濾波器設(shè)計(jì)和調(diào)制濾波器組的設(shè)計(jì)與實(shí)現(xiàn)，竝利用MATLAB軟件對(duì)所研究的內(nèi)容進(jìn)行了倣真。
In this paper we study linear phase maximally decimated FIR cosine modulated filter banks, in which each filter has linear phase and is obtained by modulating the prototype filter by cosine sequences.
現(xiàn)研究了一種具有線性相位的最大抽取FIR餘弦調(diào)制濾波器組，該濾波器組中每一個(gè)濾波器都具有線性相位，且由原型濾波器經(jīng)餘弦序列調(diào)制得到。
