Difference Between AND Gate and OR Gate

Both AND logic gate and OR logic gate are the two basic logic gates used in digital circuits. ... The crucial difference between AND gate and OR gate is that AND gate performs multiplication of the digital inputs. As against the OR logic gate is used to execute the addition of the digital inputs.

WHAT IS AND gate or gate and not gate?

The OR gate is an electronic circuit that gives a high output (1) if one or more of its inputs are high. ... This is a NOT-AND gate which is equal to an AND gate followed by a NOT gate. The outputs of all NAND gates are high if any of the inputs are low. The symbol is an AND gate with a small circle on the output.

Where is and gate used?

The AND gate is a basic digital logic gate that implements logical conjunction - it behaves according to the truth table to the right. A HIGH output (1) results only if all the inputs to the AND gate are HIGH (1). If none or not all inputs to the AND gate are HIGH, LOW output results.

What is the difference between AND gate and NAND gate?

The NAND Gate is simply an AND Gate with an inverter on the output. Therefore, whatever the output from the AND Gate is, it is inverted or flipped to the opposite state.
...
NAND Gate.

What is XOR and XNOR gate?

There are two remaining gates of the primary electronics logic gates: XOR, which stands for Exclusive OR, and XNOR, which stands for Exclusive NOR. In an XOR gate, the output is HIGH if one, and only one, of the inputs is HIGH. ... An XNOR gate is an XOR gate whose output is inverted.

How many NAND gates are required for and gate?

Now, 4 gates are essential to form NAND gates. For Input: For input it is important to have 2 NOR gates.

How many NOR gates are required for and gate?

XNOR. An XNOR gate is made by connecting four NOR gates as shown below. This construction entails a propagation delay three times that of a single NOR gate.

What is the function of OR gate?

The OR gate is a digital logic gate that implements logical disjunction – it behaves according to the truth table to the right. A HIGH output (1) results if one or both the inputs to the gate are HIGH (1). If neither input is high, a LOW output (0) results.

Why is it called an AND gate?

Basic logic gates

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 output is "true" when both inputs are "true." Otherwise, the output is "false." In other words, the output is 1 only when both inputs one AND two are 1.

What is negative or gate?

The Negative-AND Gate

A Negative-AND gate functions the same as an AND gate with all its inputs inverted (connected through NOT gates). In keeping with standard gate symbol convention, these inverted inputs are signified by bubbles.

Why is an OR gate better than an AND gate?

However, the two are mainly differentiated on the basis of logic operation performed by them. The crucial difference between AND gate and OR gate is that AND gate performs multiplication of the digital inputs. As against the OR logic gate is used to execute the addition of the digital inputs.

What are the 7 logic gates?

The basic logic gates are classified into seven types: AND gate, OR gate, XOR gate, NAND gate, NOR gate, XNOR gate, and NOT gate. The truth table is used to show the logic gate function. All the logic gates have two inputs except the NOT gate, which has only one input.

Why logic gates are used?

Computers need a way to manipulate those 1s and 0s, so that they can eventually do more complicated operations like calculating the 50th digit of π. Computers use logic gates to transform the 1s and 0s from input wires. A logic gate accepts inputs and then outputs a result based on their state.
