摘要
阐述滤波器的频率响应的振幅、相位和群延时的相关性,频率解析度对滤波器的影响,群延时与滤波器的频率波长的关系,最小相位滤波器等问题。
The correlation between amplitude,phase and group delay of frequency response,the influence of frequency resolution on filter,the relationship between group delay and frequency and wavelength of filter,and the minimum phase filter are expounded.
