Broadbandfilter: a filter that transmits a range of light waves.
阔波段滤片：能让一个范围的光波透过的滤片。

This method is especially applicable to the design of broadbandfilter which has its own complicated computation and design.
这种设计方法特别适用于本身计算、比较复杂的宽带滤波器的设计。

But to the CW pulse signal with changing carrier wave frequency, common filter cannot achieve narrowband filter, whereas broadbandfilter cannot reach the request of the signal-noise ratio.
