摘要：

It is an important to design FIR filters with maximally flat characteristics in the passband and equiripple characteristics in the stopband to reduce ringing and to maximize the stopband attenuation. The design method of such FIR filters by Remez algorithm has been proposed. However, since the delay of linear-phase filters is half of filter length, the delay of high-order linear-phase filters is large. In this paper, we present a design method of low delay FIR bandpass filters with maximally flat characteristics in the passband and equiripple characteristics in the stopband by successive projections method. The resulting filters have lower delay in die passband compared with linear-phase FIR filters with the same order.
