Abstract:
     The present invention relates to an auxiliary computing tool for calculating convolution-convolution rule. Said invented convolution rule consists of three portions of fixed scale, slide scale and turning scale, and the fixed scale label position and turning scale label position are respectively equipped with a writing board on which numerical valve can be written and can be scrubbed, and both sides of the turning scale are symmtrical and identical. The adoption of said convolution rule not only can evaluate digital linear convolution, periodic convolution and cyclic convolution, but also can visually display four steps of deconvolution, traslation, multiplying and summation in the course of evaluating convolution.
