Logic gates are the fundamental building blocks of digital circuits and systems. They perform basic logical functions that are essential for digital computing. Here are some common types of logic gates along with their properties, Boolean expressions, and truth tables:
AND Gate
The AND gate performs a logical multiplication of its inputs. It produces a high output (1) only when all its inputs are high (1). The Boolean expression for a two-input AND gate is:
Z = A.BTruth Table:
A | B | A AND B--|---|--------0 | 0 | 00 | 1 | 01 | 0 | 01 | 1 | 1OR Gate
The OR gate performs a logical addition of its inputs. It produces a high output (1) if at least one of its inputs is high (1). The Boolean expression for a two-input OR gate is:
Z = A + BTruth Table:
A | B | A OR B--|---|-------0 | 0 | 00 | 1 | 11 | 0 | 11 | 1 | 1NOT Gate
The NOT gate, also known as an inverter, produces an output that is the complement of its input. The Boolean expression for a NOT gate is:
Z = ¬ATruth Table:

A logic gate is a digital gate that allows data to be transferred. Logic gates, use logic to determine whether or not to pass a signal. Logic gates, on the other hand, govern the flow of information based on a set of rules. The following types of logic gates are commonly used: 1. AND OR 2. NOT 3. NOR 4. NAND 5. XOR 6. … See more
A logic gate is a simple switching circuit that determines whether an input pulse can pass through to the output in digital circuits. The building blocks of a digital circuit are logic gates, which execute numerous logical operations that are required by any … See more
AND Gate An AND gate has a single output and two or more inputs. When all of the inputs are 1, the output of this gate is 1. The AND gate’s Boolean logic is Y=A.B if there are two inputs A and B. Therefore, in And gate, the output is high when all the inputs are high. OR … See more
