Filters with double symmetry
A. A. Lanne, Т. В. Меркучева · Radioelectronics and Communications Systems · 2009
Effective hardware realization if digital filters assumes minimization of computational expenses. Computational expenses may be minimized by decreasing the number of multipliers. Symmetrization of amplitude-frequency characteristics and a particular case of symmetrization which is double symmetry are suggested to be used for this purpose.
