A “ TRICK ” for the Design of FIR Half-Band Filters

  title={A “ TRICK ” for the Design of FIR Half-Band Filters},
  author={Pavanapuresan P. Vaidyanathan and Truong and Quang-Loc Nguyen},
Ab.rfruct -Based on a well-known property of FIR half-hand filters, this correspondence shows how the design time for equiripple half-hand filters can be reduced by a considerable amount. The observation which leads up to this improved procedure also places in evidence new implementation schemes, which simultaneously ensure low passband and stopbund sensitivities. Extension of the method to Mth-band filter design is also outlined.
