A complete solution, accompanied with proofs, to the problem of linear-phase maximally-flat M-band filter design with prescribed centers and degrees of flatness is provided as a dedicated modular structure consisting of simple interpolating cells. The structure is easily tunable and provides a simple mechanism to vary both the centers and degrees of flatness independently at each level
