  2. Logic gate - Wikipedia

    en.wikipedia.org/wiki/Logic_gate

    A logic gate is a device that performs a Boolean function, a logical operation performed on one or more binary inputs that produces a single binary output. Depending on the context, the term may refer to an ideal logic gate, one that has, for instance, zero rise time and unlimited fan-out, or it may refer to a non-ideal physical device [1] (see ...

  3. Bitwise operations in C - Wikipedia

    en.wikipedia.org/wiki/Bitwise_operations_in_C

    In the C programming language, operations can be performed on a bit level using bitwise operators. Bitwise operations are contrasted by byte-level operations which characterize the bitwise operators' logical counterparts, the AND, OR, NOT operators. Instead of performing on individual bits, byte-level operators perform on strings of eight bits ...

  4. Adder (electronics) - Wikipedia

    en.wikipedia.org/wiki/Adder_(electronics)

    In this implementation, the final OR gate before the carry-out output may be replaced by an XOR gate without altering the resulting logic. This is because when A and B are both 1, the term ( A ⊕ B ) {\displaystyle (A\oplus B)} is always 0, and hence ( C i n ⋅ ( A ⊕ B ) ) {\displaystyle (C_{in}\cdot (A\oplus B))} can only be 0.

  5. AND gate - Wikipedia

    en.wikipedia.org/wiki/AND_gate

    The AND gate is a basic digital logic gate that implements logical conjunction (∧) from mathematical logic – AND gate behaves according to the truth table. A HIGH output (1) results only if all the inputs to the AND gate are HIGH (1). If not all of the inputs to the AND gate are HIGH, a LOW output results.

  6. OR-AND-invert - Wikipedia

    en.wikipedia.org/wiki/OR-AND-invert

    OR-AND-invert gates or OAI-gates are logic gates comprising OR gates followed by a NAND gate. They can be efficiently implemented in logic families like CMOS and TTL.

  7. XOR gate - Wikipedia

    en.wikipedia.org/wiki/XOR_gate

    XOR gate (sometimes EOR, or EXOR and pronounced as Exclusive OR) is a digital logic gate that gives a true (1 or HIGH) output when the number of true inputs is odd. An XOR gate implements an exclusive or ( ↮ {\displaystyle \nleftrightarrow } ) from mathematical logic ; that is, a true output results if one, and only one, of the inputs to the ...

  8. Logical conjunction - Wikipedia

    en.wikipedia.org/wiki/Logical_conjunction

    AND logic gate. In high-level computer programming and digital electronics, logical conjunction is commonly represented by an infix operator, usually as a keyword such as "AND", an algebraic multiplication, or the ampersand symbol & (sometimes doubled as in &&).

  9. Boolean circuit - Wikipedia

    en.wikipedia.org/wiki/Boolean_circuit

    Several important complexity measures can be defined on Boolean circuits, including circuit depth, circuit size, and the number of alternations between AND gates and OR gates. For example, the size complexity of a Boolean circuit is the number of gates in the circuit. There is a natural connection between circuit size complexity and time ...
