提出了一种改进的积分梳状(CIC) 滤波器. 在改变传统积分梳状滤波器的延迟因子的 同时,将锐化(Sharpen) 技术和相位分解技术应用于此滤波器. 改进后的滤波器与传统滤波器 相比,减少了信号失真,降低了系统功率消耗. 仿真结果表明,改进后的滤波器在通带范围内的 波动很少,而且,具有较高的阻带衰减.(An improved Integrator Comb (CIC) filter. In changing the traditional integral comb filter delay factor, we will Sharpen (Sharpen) technology and phase decomposition technique used in this filter. Improved filtering Compared with the traditional filter device to reduce the signal distortion and reduces system power consumption. The simulation results show that the improved pass-band filter in the framework of the volatility of small and with high stopband attenuation.)
