| 摘 要： | 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.并且分别用Welch法和全相位法对在有色噪声中混入的双频小信号余弦波进行谱估计,实验证明全相位谱估计性能优于经典谱估计.

| Abstract: | 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. And according to the method of Welch and All phase, the power spectrum of double frequency small signal mixed in the colored noise is estimated, the simulation proves that the all phase spectrum estimation is better than classical spectrum estimation. |
