# WHAT ARE and NOT and OR gates?

## WHAT ARE and NOT and OR gates?

The OR gate is an electronic circuit that gives a high output (1) if one or more of its inputs are high. A plus (+) is used to show the OR operation. NOT gate. The NOT gate is an electronic circuit that produces an inverted version of the input at its output. It is also known as an inverter.

## What is logic gate draw schematic symbol of not AND NOR gate?

The Boolean expression for a logic NOR gate is denoted by a plus sign, ( + ) with a line or Overline, ( ‾‾ ) over the expression to signify the NOT or logical negation of the NOR gate giving us the Boolean expression of: A+B = Q.

What is a NOT logic gate?

A NOT gate, often called an inverter, is a nice digital logic gate to start with because it has only a single input with simple behavior. A NOT gate performs logical negation on its input. In other words, if the input is true, then the output will be false. Similarly, a false input results in a true output.

### What is NOR logic gate?

The NOR gate is a digital logic gate that implements logical NOR – it behaves according to the truth table to the right. A HIGH output (1) results if both the inputs to the gate are LOW (0); if one or both input is HIGH (1), a LOW output (0) results. NOR is the result of the negation of the OR operator.

### What is NOT logic gate?

In digital logic, an inverter or NOT gate is a logic gate which implements logical negation. In mathematical logic it is equivalent to the logical negation operator (¬). The truth table is shown on the right.

What are the three ways to depict any logic gate?

For AND Gate – If both the inputs are high then the output is also high

• For OR Gate – If a minimum of one input is high then the output is High
• For XOR Gate – If the minimum one input is high then only the output is high
• NAND Gate – If the minimum one input is low then the output is high
• NOR Gate – If both the inputs are low then the output is high.
• ## What are the real life examples of logic gates?

Types of logic gates

• The OR Gate. The OR gate has two inputs marked as A and B and output as C.
• Diode OR Gate. When both A and B are at logic 0 i.e.connected to ground,both the diodes will be reverse baised at the out put will be at zero.
• OR gate truth table
• AND Gate.
• Diode AND Gate.
• AND gate truth table
• NOT Gate.
• ## What are logic gates and types of gates?

logic gates are fundamental building blocks of the digital system. NOT, OR, and AND Gates are the basic types of gates. The interconnection of gates to perform a variety of logical operation is called logic design. A truth table lists all possible combination of inputs and the corresponding outputs.

What does a logic gate look like?

Logic gate diagrams would look like this: OR gate. An OR gate has two inputs. OR tells us that EITHER Input A OR Input B has to be 1 (or ON) in order for the output to be 1. Otherwise the output is…
