This paper puts forward to a new way of generating colored noise using a novel all-filter phase digital filter. Compared to traditional FIR filter, the colored noise generated by using this filter has fewer spectrum leak, higher stop band attenuation.
本文提出用全相位数字滤波器这种新型滤波器滤波白噪声产生有色噪声的方法，这种方法比用传统FIR滤波器产生的有色噪声频谱泄漏少，阻带衰减功率大等优点。
The filter has not only wider stop band but also decreased dimension ( approximately 40% shorter) comparing with traditional direct-coupled half wave resonator ones.
与传统的直接耦合半波长谐振腔型带通滤波器相比，这种滤波器带外抑制度高，阻带宽，特别是其尺寸缩短了近40%。
On this basis, a new type of non-symmetric DGS filter is proposed, designed and produced. The results of simulation and test show that this filter has quasi-elliptic function characteristics and its stop band attenuation is deep.
