An Extreme Simple Method for Digital FIR Filter Design

An extreme simple method for digital FIR filter design is introduced. A series of filter formulas are obtained. In comparison with existed methods the method is the simplest except rectangular window method. Filter transition bandwidth is smaller than 4.65π/N for filter order N. For the same filter specifications filter order obtained by using the new method is much smaller than by using Kaiser window if minimum stop band attenuation is in the range of 39.5db to 48.5db and corresponding maximum pass band ripple is from 0.35db to 0.18db.
