Explanation

A Karnaugh map (K-map) is a visual method for simplifying Boolean expressions.

It consists of square boxes called cells, each representing a minterm (combination of variable values).

Explanation

A logic gate is a basic building block of a digital circuit that performs logical operations (AND, OR, NOT).

It processes binary inputs (0s and 1s) to produce a single binary output.

Explanation

Explanation

The Karnaugh map (K-map) method was introduced by Maurice Karnaugh in 1953.

It is used for simplifying Boolean algebra expressions visually.

Explanation

A NAND gate gives output 0 only when all inputs are 1; otherwise, it outputs 1.

It is the inverse (NOT) of the AND gate.

Explanation

In Karnaugh Maps, 1's are grouped in powers of two (1, 2, 4, 8, etc.) horizontally or vertically to simplify Boolean expressions.

The goal is to minimize the number of terms by forming the largest possible groups of adjacent 1's.

Explanation

The AND gate performs logical multiplication, outputting 1 only when all its inputs are 1.

It is also known as a conjunction gate in digital logic.

Explanation

Logic gates are the fundamental building blocks of digital systems.

The AND, OR, and NOT gates are the most fundamental logic gates.

The NAND and NOR gates are called universal gates because they can be combined to produce OR, AND, and NOT gates.

Explanation

A 3 to 8 decoder has three inputs (A, B, C) and eight outputs (D0 to D7).

Explanation

Different logic gates are AND,OR , NOT, NAND, NOR.

logic gates are elementary  building block of digital circuit.

Most of logic gates have two input and one output.
