This paper proposes a new technique for designing 2-D diamond-shaped half-band FIR filters with maximally flat amplitude property. First, a 2-D half-band FIR filter is defined and several interesting properties of this filter are explained. Then a design method using these properties is explained and some design examples are shown. Finally, we discuss the advantages of our method by comparing with the previously proposed method.
