Term | Definition | Example |
---|---|---|

DeMorgan's Theorems | 1) Theorem stating that the complement of a sum (OR operation) equals the product (AND operation) of the complements, and 2) Theorem stating that the complement of a product (AND operation) equals the sum (OR operation) of the complements. | DeMorgan's Theorems is used by many engineers today. |

Distributive Property | Full name: distributive property of multiplication over addition. The property that allows us to distribute ("multiply through") an AND across several OR functions. For example, a(b+c)=ab+ac. | We have done distributive property in class today. |

Least Significant Bit (LSB) | The rightmost bit of a binary number. This bit has the number's smallest positional multiplier. | The binary number has a least significant bit. |

Logic Circuit | Any circuit that behaves according to a set of logic rules. | Control systems make use of logic circuits |

Logic Diagram | A diagram, similar to a schematic, showing the connection of logic gates. | Circuits that contain any sort of gate, has a logic diagram. |

Maxterm | A sum term in a Boolean expression where all possible variables appear once in true or complement form. | That OR gate has a maxterm. |

Minterm | A product term in a Boolean expression where all possible variables appear once in true or complement form. | The numbers were expressed as a minterm. |

Most Significant Bit (MSB) | The leftmost bit in a binary number. This bit has the number's largest positional multiplier. | The Binary code has the most significant bit. |

Product-of-Sums (POS) | A type of Boolean expression where several sum terms are multiplied (AND'ed) together. | Product of sums has a great connection with the maxterm |

Product Term | A term in a Boolean expression where one or more true or complement variables are AND'ed. | That AND gate is an example of a product term |

Sum-of-Products (SOP) | A type of Boolean expression where several product terms are summed (OR'ed) together. | Every truth table has a sum of products which allows someone to read when something is on. |

Sum Term | A term in a Boolean expression where one or more true or complement variables are OR'ed. | That OR gate is an example of a sum term. |

Truth Table | A list of all possible input values to a digital circuit, listed in ascending binary order, and the output response for each input combination. | Many circuits have a truth table. |
