An efficient algorithm is presented for performing optimal Chebyshev approximation in the absence of the Haar condition. It has been successfully used in the design of two-dimensional FIR low-pass filters with and without symmetry constraints in the impulse response and also in the design of special classes of one-dimensional FIR filters with impulse response constraints such as interpolation filters.
