摘　　要：提出了一种非等纹响应低通滤波器.不同于传统的等纹响应低通滤波器,该滤波器在通带内具有非等纹的特性,通过调节低通滤波器通带内的反射波瓣的幅度,可将靠近通带边沿部分的反射波瓣设置得更低,可有效改善滤波器的通带边沿特性.In this paper, a lowpass filter with non-equiripple responses was presented. Different from traditional equiripple filters, the passbands of the proposed filter were non-equiripple. Through the adjustment of the amplitude of the reflection lobes in the passbands of lowpass filter, the amplitude of the reflection lobes near the band edge could be assigned to be lower, which was good for improving the performance of the band edge of the filter.
