Universal Gates Basics
A gate type that alone can implement any Boolean logic function.
What is a universal gate?
An OR gate can be created by adding this element to a NOR gate’s output.
What is an inverter?
The NAND gate performs the inversion of which basic logic operation?
What is AND?
AOI stands for this type of logic structure.
What are AND‑OR‑INVERT gates?
A graphical method used to simplify Boolean logic expressions.
What is a Karnaugh Map?
A NOR gate outputs a logic HIGH only when both inputs are this value.
What is 0?
A NOR gate becomes an inverter when this is done to its inputs.
What is tying the inputs together?
A NAND gate acts as a NOT gate when its inputs are this way.
What is connected together?
The first step in converting a logic expression to NAND or NOR logic.
What is implementing the circuit using AOI gates first?
K‑Maps are practical for circuits containing up to this many variables.
What is four variables?
A NAND gate outputs a logic LOW only when both inputs are this value.
What is 1?
Creating an AND gate using NOR requires this Boolean concept.
What is DeMorgan’s Theorem?
An OR gate can be implemented with NAND gates by applying this principle.
What is DeMorgan’s Theorem?
A back‑to‑back inverter pair results in this simplified effect.
What is no inversion?
K‑Map cells are arranged so that only one variable changes between adjacent cells.
What is true?
Using only one gate type can reduce this aspect of a circuit design.
What is the number of integrated circuits (ICs)?
Name one step in the NOR implementation procedure after AOI design.
What is replacing AND/OR/NOT gates with NOR equivalents?
What must be removed when simplifying a NAND‑only circuit?
What are double inversions?
After eliminating unnecessary inversions, the circuit must be done again.
What is redraw the circuit?
Valid K‑Map groupings must be this type of number.
What is a power of two?
The two logic gates classified as universal gates.
What are NAND and NOR gates?
Showing that two logic circuits behave the same for all inputs is called this.
What is proof of equivalence?
Using a single 74LS00 IC replaces three AOI ICs when implementing this logic style.
What is NAND logic?
Fewer ICs in a design generally result in this benefit.
What is lower cost?
Treating an X as a 1 in a K‑Map helps accomplish this goal.
What is creating larger groups for simpler expressions?
