چکیده
In this paper, the two dimensional (2-D) frequency sampling fllter system function described in reference [1] is further developed for frequency sampling filters that have linear phase and frequency sampling fllters that have linear phase and fourfold symmetry. Theresulting system functions are computationally more efficient for implementing frequency sampling filters with linear phase and frequency sampling filters with linear phase and fourfold symmetry than the system function described in reference [1].
