Abstract: A simplified method has been proposed for finding two-dimensional convolute integers, including central and non-ecentral point evaluation and multi-convolution integers. The results are equal to the corresponding reports, but the calculation is much simple. The performance of 2D-convolution for the detection of a minor compound in the presence of a main one is also discussed.

Key words: 2D-convolution, Orthogonal combination, Peak purity assessment
