band-limited function

In addition, the stop-band rejection can be further increased by using elliptic filter function which has limited frequency transmission zeros.

另外，在函数类型上使用椭圆函数型，使带外出现有限频率传输零点，进一步提高了带外抑制能力。

By introducing the prior information constraint in the objective function, we can solve the ill-posed problem and band-limited problem for the impedance inversion.

通过在目标函数中增加先验知识约束，我们可以解决波阻抗反演的病态问题及带限问题。

Next, by the orthogonal multiresolution analysis, the necessary conditions of a kind of M-band band-limited orthogonal wavelet function constructed by the scaling function are proposed.

然后利用正交多分辨率分析，给出由该尺度函数构造的一类频带有限的M进制正交小波函数的必要条件。
