Electronic multiplier-divider circuit - contains switchable adder-subtractor circuits and output stage requiring no potential storage series circuit

摘要

The electronic multiplier-divider circuit consists of a number of adder-subtractor circuits which are switchable between addition and substraction. The number of circuits (1) can be held sufficiently low by using shift registers extended in a suitable direction and by restricting the multiplicand and divisor to fewer than eight digits. The output stage (N) contains two shift registers with opposed shift direction or only one shift register for both directions. No additional potential storage series circuit is required in the output stage. ADVANTAGE - Eliminates need for potential storage series circuit.
