波数字滤波器由两端终接电阻负载的无源LC梯形滤波器导出的一种数字滤波器结构。应用双线性变换S=k(1-Z-1)/(1+Z-1)可将用波参数描述的无源元件,实现为数字元件。表1列出了无源元件R、C、L及其对应的由延时单元、乘法器和加法器构成的数字元件。通常高阶递归型数字滤波器的级联型或并联型有产生极限环振荡的危险。此外,在输入信号非常小时,由于舍入误差的高度相关，也可能导致数字滤波器的不稳定而产生固定振荡。1971年，提出波数字滤波器的伪无源性概念，并论证了这种数字滤波器的低灵敏度特性。波数字滤波器具有良好的稳定性，可以用较短的系数字长实现，有良好的动态范围，不会出现极限环振荡（即在环路情况下应用也不会出现任何杂散振荡）。这种数字滤波器特别适用于通信系统。在波数字滤波器结构中，用波参数描述的元件，在联接时必须遵从端口间阻抗匹配的原则。相应地，数字元件之间的联接按其为串联或并联分别采用由乘法器和加法器构成的串联适配器或并联适配器匹配联接。适配器符号及其对应的联接关系见表2。图为三阶椭圆型低通LC 梯形滤波器及其等效的波数字滤波器。波数字滤波器的另一种结构称为波格型数字滤波器，是由对称型或格型无源LC 滤波器导出的。参考书目A.
