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 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.
