TermDefinitionExample
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.
