An important property of a half-band filter is that half of its coefficient values are trivial. This yields significant advantage in terms of its computational complexity. Nevertheless, the complexity of a half-band filter is still very high if its transition-width is very narrow. In this letter, we introduce a novel method for the synthesis of very sharp half-band filter using the frequency response masking technique
