According to coupled wave theory, the volume hologram has a good property for light filtering and can be used as a kind of narrow-bandfilter.
根据耦合波理论,体积全息图有很好的滤光特性,可以作为一种窄带滤光片在实际中得到应用。

Finally, the S-CDMA and the adaptive nonlinear filter techniques are used to restrain the impulse interference and the narrow-band continuous wave interference.
最后,采取了同步码分多址技术和非线性自适应滤波技术来抑制冲击干扰和窄带连续波干扰。
