本文介绍了根据给定滤波器技术指标能自动确定贝塞尔滤波器阶数，并计算出相应的滤波器传输函数和时延函数的一种计算程序。

In this paper the flow charts of the computer programs are given for automatically determining the order of the filter as well as calculating the transfer and time-delay functions once the technical requirements are given .

同时提出基于贝塞尔滤波器的全通恒时延滤波器，其幅度特性恒定，而且在低频范围内具有恒定的延迟时间。

A all-pass with constant time delay based on Bessel filter is Put forward at the same time , its amplitude response is constant , there are constant relay time within the scope of low frequency .

首先介绍了如何用分离元件来设计典型滤波器如贝塞尔滤波器、巴特沃斯滤波器，切比雪夫滤波器等的方法。然后讨论了采用集成电路芯片来设计抗混叠滤波器的方法。

It starts by guiding the reader through the design process for the basic filters like Butterworth , Chebyshev , and Bessel with separate components , it then goes on to introduce designing anti-aliasing filters using integrated circuits .

所实现的二维数字滤波器不仅保持贝塞尔滤波器通带内相位线性、阻带内相位近似线性的优点，而且能利用一维至二维的双线性变换压缩过渡带，使过渡带变得陡峭、阻带衰减增加。

The realized 2-D IIR filters not only keep the advantages of the linear phase charateristics in the pass band and approximately linear phase charateristics in the stop band , but also compress the transition band to be steep and increase the attenuation of stop - band .

贝塞尔型滤波器具有优良的时延性，因而常用于选择性要求低而时延性要求高的场合。

Because of its good time-delaying Character , Bessel filters are widely used when selectivity is not so important , and time-delaying performance is highly demanded .
