Digital multiplier or divider circuit - provides single key operation to generate inputs for arithmetic operations

摘要

An electronic multiplier-divider circuit provides for numbers coded in 5211 weighting to be processed and the result generated with the same weighting. The circuit has a keyboard for entry of the dividend, when used in the division mode, into two shift registers (3,5). A division key is operated and the process is executed when a second key is actuated. The signals required for operating in either division of multiplication mode are generated by a control circuit. Multiplication can be selected by a signal key actuation. ADVANTAGE - Efficient digital multiplication.
