Horses live in a monochrome world .light visible to human eyes however occupies only a very narrowband in the whole electromagnetic spectrum.
然而，人眼可见的光在整个光谱中只占一个非常狭窄的频段。

A lot of complex functions, such as 1/3 octave analysis, sound power, tonality narrowband analysis, vibration spectrum, have been solved.
解决噪声1/3倍频程、声功率、音调窄带谱，振动频谱等复杂功能的在线分析与处理。

Computer simulations show that it is superior to the conventional approaches in most cases and thus is a good approach for narrow-band interference suppression in spread spectrum systems.
