Variable position multiplying circuit - includes switch with four OR=gates, each with two inputs and seven diodes

摘要

The main circuit consists of 28 product and circuits, each with 2 inputs and 26 diodes. One OR circuit has 5 inputs, another 4, another 3, another 4, and a further one 5. The input circuit consists of 9 AND circuits, each with 2 inputs and 4 AND circuits, each with 2 inputs and 7 diodes. The code conversion circuit consists of 9 AND circuits, each with 2 inputs and 2 inverters and an OR circuit with 4 inputs. ADVANTAGE - Improvement on previous patent which had a failing in that not all the necessary diodes were present.
