Karnaugh Map

A diagram used in Boolean algebra and digital logic design to simplify logic functions.

NAND Gate

A digital logic gate that produces an output that is false only if all its inputs are true.

NOR Gate

A digital logic gate that produces an output that is true only if all its inputs are false.

Majority Function

A logic function that outputs true if the majority of its inputs are true.

Gray Code

A binary numeral system where two successive values differ in only one bit.

Excess-3 Code

A non-weighted code used to express decimal numbers, where each digit is represented as its equivalent 4-bit binary number plus three.

BCD Code (Binary-Coded Decimal)

A class of binary encodings for decimal numbers where each digit is represented by its own binary sequence.

Half Adder

A digital circuit that calculates the sum of two bits, producing a sum and a carry.

Full Adder

A digital circuit that adds three bits (two significant bits and a carry bit) and produces a sum and a carry output.

Combinational Circuit

A type of logic circuit whose output is determined solely by its current inputs, without regard to past inputs or outputs.
