May 3 • General • 11380 Views • 2 Comments on Truth table of OR Gate

Here first of all we have to get a brief idea about gates and truth table.

Logic Gates:

• A logic gate is a physical device which performs logical operation in one or more logical inputs and produce a single logical output.
• Logic gates process signals which represents true or false.
• Logic gates are identified by their function i.e.,
1. NOT
2. NAND
3. AND
4. OR
5. NOR
6. EX-OR
7. EX-NOR

TRUTH TABLE:

Truth table is a table which shows the shows the output state depending upon the possible combination of input states.It shows the function of a logic gate.

OR Gate:

• An OR Gate is an electronic circuit that gives a true output (1) if one or more of its input are true.
• (+) is used to show the OR operation.
•  For a 2-input OR Gate, the output Q is true if either input “OR” input B is true.
• The Boolean expression of OR Gate is:

Q=A or B

•  An OR gate can have two or more inputs, its input is true if atleast one input is true.
•  OR is used to set the bits to one.
• symbol or truth table of OR gate is as follows: Related questions:

Q1. What do you mean by Logic Gates? What are the different kinds of logic gates?

Ans.  A logic gate is a physical device which performs logical operation in one or more logical inputs and produce a single logical output. Logic gates process signals which represents true or false.

Different kinds of Logic gate are as follows:

1. NOT
2. NAND

4. OR
5. NOR
6. EX-OR
7. EX-NOR

Q2. What is a truth table?

Ans.   Truth table is a table which shows the shows the output state depending upon the possible combination of input states.It shows the function of a logic gate.

Q3. What is OR Gate?

Ans  An OR gate can have two or more inputs, its input is true if atleast one input is true.OR is used to set the bits to one.
