ABSTRACT:
High accuracy function calculating apparatus using a minimum of components and storage locations. Second difference values of the function to be generated are stored in a read-only memory which is addressed by an incrementable and reversible address counter. A first accumulator circuit connected to the output of the read-only memory calculates the first difference values of the function. A second accumulator coupled to the output of the first accumulator calculates the values of the desired function. The apparatus is used to advantage in radar azimuth converter applications as well as in general purpose function calculating applications.
