✦ Synopsis
This paper discusses a least-squares error design of 2-D digital filters under a peak error constraint. Initially we present a filter design procedure in which the peak error constraint is satisfied by iterating the design based on a weighted least-squares error criterion to update the weights. The computational complexity required in the filter design is then reduced by switching from the above procedure to the Lagrange method of unknown constants during the course of iteration. Finally, the trade-off between square error and absolute peak error is verified by using a numerical example.
