Today, I want to design a bandpass filter with very narrow bandwidth about 0.05*pi. But I don't have many delays. I just have about 3 delays. If I use a 7-tap FIR, I can't design a suitable filter satisfying the bandwidth required. But if I use a IIR filter that satisfies the bandwidth requirement, the group delays of this filter is about 25 delays.
Can anyone help me to design a filter satisfies both requirements?
