What is the function of AND gate?

What is the function of 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. 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 truth table for AND gate?

Truth tables A truth table is a good way to show the function of a logic gate. It shows the output states for every possible combination of input states. The symbols 0 (false) and 1 (true) are usually used in truth tables. The example truth table shows the inputs and output of an AND gate.

What do you mean by AND gate?

An AND gate is an electrical circuit that combines two signals so that the output is on if both signals are present. An AND gate has two or more inputs and one output, and if the inputs applied to it are all 1, then the output will be 1.

IS AND gate multiplication?

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.

WHY AND gate is called coincidence gate?

Answer: Coincidence means an occurrence of two same things at the same time and a detector which detects it is called a coincidence detector. It gives high output when both the inputs are high/same or they coincide otherwise it remains low. Hence, serving as a coincidence detector.

Why XOR gate is called an inverter?

Why XOR gate is called an inverter? Explanation: The XOR (Exclusive Or) gate has a true output when the two inputs are different. When one input is true, the output is the inversion of the other. When one input is false, the output is the non-inversion of the other.

What is Boolean function with example?

A Boolean function is a function that has n variables or entries, so it has 2n possible combinations of the variables. These functions will assume only 0 or 1 in its output. An example of a Boolean function is this, f(a,b,c) = a X b + c. These functions are implemented with the logic gates.

WHY IS AND gate multiplication?

The multiplication comes second for frequency of use. An “AND” gate multiplies two bits. To multiply two n-bit numbers A and X, n2 “AND” gates are required.

What is negative OR gate?

An OR gate with inverted inputs is called a negative OR gate, and an AND gate with inverted inputs is called a negative AND gate. Thus, a NAND gate is equivalent to a negative OR gate.

Which gate is known as coincidence gate?

AND logic gates is known as a coincidence detector. Coincidence means an occurrence of two same things at the same time and a detector which detects it is called a coincidence detector. It gives high output when both the inputs are high/same or they coincide otherwise it remains low.

How many NOR gates are required to make an OR gate?

two NOR gates
OR: You need two NOR gates to create an OR gate. The first NOR gate returns LOW if either input is HIGH or both inputs are HIGH. Then the second NOR gate is configured as a NOT gate to invert the output of the first NOR gate.

What is the working principle of an AND gate?

An AND gate is a logic gate having two or more inputs and a single output. An AND gate operates on logical multiplication rules. In this gate, if either of the inputs is low (0), then the output is also low. If all of the inputs are high (1), then the output will also be high.

How to explore the function of logic gates?

Conclusion: In this lab, I explored the function of the basic logic gates. I learned how to implement them on a breadboard with integrated circuits. I tested the output voltage of the breadboard circuits using the multi-meter, and ensured the results corresponded with the truth table of the logic gate tested.

What is the relation between input and output of an AND gate?

The relation between input and output values can be explained using the AND Gate Truth Table shown below. The equations output can be easily explained using the AND Gate Boolean Equation, which is Q = A x B or Q = AB. Hence, for an AND Gate the output is HIGH only when both the inputs are HIGH.

How is a and Gate represented in a circuit?

The circuit represents both the inputs A & B for the AND gate and Output, Q which also has a +5V supply to the collector of the first transistor which is connected in series to the second transistor and an LED is connected to the emitter terminal of the second transistor.
