ABSTRACT:
Digital signal processing arrangement such as a digital filter for computing output signal samples which are each equal to the sum of products of a given plurality of pairs (for example N) of input signal samples. One of the input signal samples of the pair is, for example, formed each time by a sample x(n) of a digital signal to be filtered, the other input signal sample of the pair by a filter coefficient z(n), wherein either the sample x(n) or the filter coefficient z(n) can assume only a limited number of values 0, .+-.A.sub.1, .+-.A.sub.2, . . . .+-.A.sub.M, M being much smaller than N. In the case x(n) can assume only this limited number of values, z(n) is first multiplied, owing to the x(n) belonging to the pair, by the sign of x(n) for generating a product of the form z(n). sgn [x(n)]. In-dependent of the magnitude of n(n) this product is applied to an accumulator which corresponds with this magnitude of x(n). N products have been applied to one of the M accumulators the partial sums stored therein are multiplied by the magnitude .vertline.x(n).vertline. corresponding therewith and the products obtained are added together.
