Abstract:

In the first paper some features of two-dimensional matrix structures and methods of their materialization in the form of physical matrices are considered. Calculated for various combinations of variables a and b values of function c are arranged as a matrix. Inputs are pulse signals applied to rows and columns of the matrix they correspond to specified numbers out of the natural set 1, 2, 3,....,N. The above simple matrix is applied to a measurement case where the number of output quantization levels is commensurable with the number of discrete values of the input formulas for errors are deduced. The matrices can be materialized by means of ferrite cores or multiwinding pulse transformers with diode isolators. In the second paper a new approach to designing matrix-type decimal arithmetic units is described, and some of the circuits are detailed A ten-state matrix is a rectangular lattice of conductors with AND-gates in the intersections. Such matrices built as integrated blocks can be used for addition, subtraction, and multiplication of two single-digit numbers. Formulas for the number of matrices required for exact and approximate arithmetic operations are given.
