The NAND Gate is a universal logic gate, using which we can implement any other type of logic gate or logical expression. Read this tutorial to understand how you can implement a XOR gate using only NAND gates. Let's start with a basic overview of XOR and NAND gates What is a XOR Gate? The XOR (Exclusive-OR) Gate is a type of derived logic gate. The XOR gate is a logic gate that has two inputs and one output. The XOR gate produces a HIGH (Logic 1) output when one and only one of its two inputs are HIGH (Logic ... Read More

As we know, the NAND Gate is a universal logic gate, using which we can implement any other type of logic gate or logical expression. Read this tutorial to find out how you can implement an XNOR gate using only NAND gates. Let's start with a basic overview of XNOR and NAND gates. What is an XNOR Gate? The XNOR (Exclusive-NOR) Gate is a type of derived logic gate. The XNOR gate is a logic gate that has two inputs and one output. The XNOR gate produces a HIGH (Logic 1) output when both of its inputs are equal, i.e. ... Read More

An OR Gate is a basic logic gate that gives a HIGH or Logic 1 output, when any of its inputs is HIGH. Whereas, the NOR gate is a universal logic gate, which gives a HIGH output only when all its inputs are LOW or Logic 0. Before, going into the implementation of OR Gate using NOR Gate, let us discuss the basic theory of OR gate and NOR gate first. What is an OR Gate? An OR Gate is a basic logic gate. An OR gate can have two or more than two inputs, but has only one output. ... Read More

NAND Gate is a universal logic gate, using which we can realize any logic gate. Read this tutorial to find out how you can realize an OR gate using a NAND gate. Before going into the implementation part, let's have a brief overview of OR and NAND gates. What is an OR Gate? An OR Gate is a basic logic gate. An OR gate may accept two or more than two inputs, but gives only one output. The OR gate gives a HIGH (Logic 1) output if any one of its inputs is in the HIGH or Logic 1 state, ... Read More

A NOT Gate is a basic logic gate that gives an output which is complement of its input. A NOR gate is a universal logic gate that can be used to implement any other type of logic gate. A NOR gate is basically an OR gate followed by a NOT gate. Read this tutorial to find out how you can implement a NOT gate using NOR gate. Let's start the discussion with a brief overview of NOT and NOR gates. What is a NOT Gate? In digital electronics, a NOT gate is a basic logic gate that has only one ... Read More

NOR and NAND gates are universal logic gates, using which we can implement any logic gate or any other logical expression. Read this tutorial to find out how you can implement a NOR gate using a NAND gate. What is a NOR Gate? NOR Gate is a type of universal logic gate, because this logic gate can be used for implementation of any other type of logic gate. NOR means "NOT + OR". That means the OR output is NOTed or inverted. Therefore, the NOR gate is a combination of OR gate and a NOT gate. $$\mathrm{NOR\:Gate = OR\:Gate \:+\:NOT\:Gate}$$ ... Read More

A Boolean function is a logical expression that returns a Boolean value, which is a value that is either TRUE or FALSE. In digital electronic circuits, the logic gates are used to implement a conditional or logical or Boolean expressions. A logic gate is a digital circuit that performs a specific logical operation on one or more input variables or signals and generates an output signal. The output of a logic gate is determined by its logical function, which is based on Boolean algebra. In digital electronics, there are several types of logic gates available such as AND gate, OR ...

An AND Gate is a basic logic gate that performs the binary multiplication, i.e., it gives a HIGH or Logic 1 output, only when all its inputs are in HIGH or Logic 1 state. On the other hand, a NOR gate is a type of universal logic gate. Therefore, NOR gate can be used to realize any other type of logic gate. Before going into the implementation of AND gate using NOR gates only, let us discuss the basic theory of AND Gate and NOR Gate first. What is an AND Gate? An AND Gate is a basic logic gate. ... Read More

As we know that the NAND Gate is a universal logic gate, therefore using the NAND gate, we can implement any logic gate or any other logical expression. Read this tutorial to understand how you can implement an AND gate using NAND gate. Let's start with a basic overview of AND and NAND gates. What is an AND Gate? An AND Gate is a basic logic gate. An AND gate may have two or more than two inputs, but gives only one output. The AND gate gives a LOW (Logic 0) output if any one of its inputs is in ... Read More

We can realize or implement a Boolean expression or a logic function as hardware using logic gates. The easiest method of implementing a logic function as hardware using logic gates is to start with the output and moves towards the inputs. The implementation of a logic function with the help of logic gates involves connecting different logic gates in a specific manner. In this article, we shall confine our attention to implementing a logic function using the OR and AND gates only. Let's start the article with a brief introduction of OR and AND gates. What is an OR Gate? ... Read More
