What is combination of logic gates?

Combinational Logic Circuits are made up from basic logic NAND, NOR or NOT gates that are “combined” or connected together to produce more complicated switching circuits. These logic gates are the building blocks of combinational logic circuits.

Which logic gate is required to realize all the logic functions?

NAND gates
By using only NAND gates, we can realize all logic functions: AND, OR, NOT, X-OR, X-NOR, NOR. So this gate is also called universal gate. The output of a to input X-OR gate is shown by: Y = A’B + AB’. This can be achieved with the logic diagram shown in the left side.

What is the most important logic gate?

The AND and NAND gates are possibly the most widely used form of logic gate that are used. Of the two the NAND gate is the most widely seen. OR / NOR : OR gates and NOR gates are another form of logic gate that form one of the basic building blocks of digital technology.

How many logic gates do you need?

There are seven basic logic gates: AND, OR, XOR, NOT, NAND, NOR, and XNOR. The AND gate is so named because, if 0 is called “false” and 1 is called “true,” the gate acts in the same way as the logical “and” operator. The following illustration and table show the circuit symbol and logic combinations for an AND gate.

Which logic gate is a combination of OR and NOT gate?

NAND gate
The combination of an AND gate and a NOT gate is called a NAND gate, as shown in the diagram.

Which logic gate does this truth table describe?

The following Truth Table compares the logical functions of the 2-input logic gates above….Summary of 2-input Logic Gates.

Logic Function	Boolean Notation
OR	A+B
NOT	A
NAND	A .B
NOR	A+B

What is the combination of gates from universal gates?

A NOR gate is a universal gate, meaning that any other gate can be represented as a combination of NOR gates.
