# Lesson 2.1 Key Terms

Term | Definition | Sentence |
---|---|---|

Logic Circuit | Any circuit that behaves according to a set of logic gates | In order to set up the logic gates you have to use the logic circuits |

Logic Diagram | A diagram, similar to a schematic, showing the connection of logic gates | I didn't understand how the logic gates were connecting so i looked at the logic diagram |

Maxterm | A sum term in a Boolean expression where all possible variables appear once in true or complement form | When a sum term has all the possible variables appearing once it's an example of a maxterm |

Most Significant Bit | The leftmost bit of a binary number. This bit has the number's largest positional multiplier. | The most significant bit has the greatest numerical value |

Product-of-Sums | A type of Boolean expression where several sum terms are multiplied together. | When the sum terms are multiplied together then it's an example of product-of-sums |

Product Term | A term in Boolean expression where one or more true or complement variables are AND'ed | I learned that a product term complements variables that are AND'ed |

Sum-of-Products | A type of Boolean expression where several product terms are summed together | When the sum terms are added together then it's an example of sum-of-products |

Sum Term | A term in Boolean expression where one or more true or complement variables are OR'ed | There is a lot of Boolean expressions such as sum term which complement variables that are OR'ed |

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 | I showed my truth table to my instructor to present him possible input values |

Minterm | A product term in a Boolean expression where all possible variables appear once in true or complement form | When the product terms has all the possible variables appearing once then it's an example of a minterm |

DeMorgan's Theorem | Theorem stating that the complement of a sum equals the product of the complements and stating that the complement of a product equals the sum of the complements | I used DeMorgan's Theorem to see if the sum equals to the product |

Distributive Property | The property that allows us to distribute across several OR functions | Several OR functions allows you to use distributive property |

Least Significant Bit | The rightmost bit of a binary number. This bit has the number's smallest positional multiplier | The least significant bit has the lowest numerical value |
