Editing Logic Circuit (section)

=== Electronic Gates ===
The elemental components of a logic circuit are [https://en.wikipedia.org/wiki/Logic_gate logic gates] — discrete [https://en.wiktionary.org/wiki/electronic electronic] [https://en.wiktionary.org/wiki/switching switching] elements that accept one or more [https://en.wiktionary.org/wiki/binary binary] inputs and produce a single binary output according to a defined logical [https://en.wiktionary.org/wiki/function function]. The fundamental gate types include:

! Gate !! Symbol !! Boolean Expression !! Description
|-
| [https://en.wikipedia.org/wiki/AND_gate AND] || · || A · B || Output is 1 only when ''all'' inputs are 1
|-
| [https://en.wikipedia.org/wiki/OR_gate OR] || + || A + B || Output is 1 when ''at least one'' input is 1
|-
| [https://en.wikipedia.org/wiki/Inverter_(logic_gate) NOT] || ¬ / ′ || Ā || Output is the logical inverse of the input
|-
| [https://en.wikipedia.org/wiki/NAND_gate NAND] || ↑ || &not;(A · B) || Complement of AND; universal gate
|-
| [https://en.wikipedia.org/wiki/NOR_gate NOR] || ↓ || &not;(A + B) || Complement of OR; universal gate
|-
| [https://en.wikipedia.org/wiki/XOR_gate XOR] || ⊕ || A ⊕ B || Output is 1 when inputs ''differ''
|-
| [https://en.wikipedia.org/wiki/XNOR_gate XNOR] || ⊙ || &not;(A ⊕ B) || Output is 1 when inputs are ''equal''
