Abstract :
In this paper we describe an algorithm for minimax design of two-dimensional FIR linear phase digital filters. A recently proposed minimax algorithm due to Charalambous in conjunction with Powell´s conjugate direction algorithm will be used to obtain the optimum results. Optimal results obtained using the present approach on a large number of design examples are presented. Also a detail discussion on the effect of various symmetries of the impulse response on the amplitude response of the filter is presented.
