New design procedures for FIR filter design are presented. The starting point is constituted by an already presented MAXFLAT design of halfband low-pass filter. The main advantage of the design lies in the fact that its tap-coefficients are given by explicit formulae. Here, by means of some frequency transforms, the author derives centro-symmetric band-pass and band-stop FIR filters. Some numerical experiments show that the present filters provide performance comparable with those offered by equiripple prototypes.
