Find out how a digital technique performs multiplication on two bitstreams and avoids the cost of the analog multiplier.

Learn about digital data and how computers understand it, including binary, denary, hexadecimal numbers, units of data, character sets and logic gates.

Learn how to generate a truth table for logic circuits, boolean expressions, and propositional formulae using a Truth Table generator.

To work out what the final output will be, the truth tables must be used to track the outputs and inputs along the combination of logic gates, like working out a puzzle.

All told it simulates seven logic gates, four flip-flops, and includes a four-bit counter. On one end of the ruler a CR1220 battery feeds the 18F43K20 which is performing the logic operations ...
