ABSTRACT:
An electronic network division system is operated responsive to signals representing divisors and dividends. An input divisor signal is divided into a given number (N) of integers, the number (N) being selected on a basis of a desired accuracy index. Each divided signal is a transform of a divisor which is read from one of (N) number of read-only memories, there being a separate read-only memory for each of the given number (N) of integers. Each of said given number of transformed divisor signals is separately multiplied by a dividend signal to produce (N) number of multiplication products. Each of these multiplication product signals is divided into high and low subproduct signals and applied to a corresponding one of (N) number of adders. A high subproduct signal from one multiplication product is added in the adding means to a low subproduct signal from another multiplication product.
