In this paper, based on Chi-Chiou's weighted least-squares (WLS) Chebyshev approximation method which is for the design of one-dimensional (1-D) FIR digital filters with arbitrary complex frequency response, we propose a new iterative W L S Chebyshev approximation method for the design of two-dimensional (2-D) FIR digital Alters with arbitrary complex frequency response. Several design examples are provided to justify the good performance of the proposed approximation method. 0-7803-1 254-6/93$03.00 0 1993 IEEE 898
