## What is logic gate truth table?

The table used to represent the boolean expression of a logic gate function is commonly called a Truth Table. A logic gate truth table shows each possible input combination to the gate or circuit with the resultant output depending upon the combination of these input(s). Input Combination 1.

## What is the truth table AND logic symbol of a three input OR gate?

### What is a logic gate draw the symbols of AND AND OR gates?

When the input is ‘high’ or ‘1’, its output is ‘low’ or ‘0’. That is, it produces a negated version of the input at its output. Hence, NOT gate is called an inverter….Solution.

Input | Output |
---|---|

X | Y |

0 | 1 |

1 | 0 |

### What is the symbol of an AND gate?

The AND gate is a basic digital logic gate that implements logical conjunction (∧) from mathematical logic – it behaves according to the truth table above.

**What is the symbol of XNOR gate?**

The logical XNOR operation is represented by ⊙. That is a dot surrounded by a circle.

**Which gate is known as universal gate?**

NAND and NOR gates

A universal gate is a gate which can implement any Boolean function without need to use any other gate type. The NAND and NOR gates are universal gates.
