ABSTRACT:
A product-sum device has a data register and a coefficient register and calculates the sum of products of the outputs of the data register and coefficient register. The data register has register elements that successively shift presently held data whenever new data is supplied to the data register. The coefficient register has register elements corresponding to the register elements. The product-sum device carries out a filtering operation at high speed.
