## NOT AND OR gate using NAND gate – circuit diagram

Earlier we discussed the basic logic gates with truth table, circuit diagram and Boolean expression. The three basic logic gates in Computers are OR gate, AND gate and NOT gate. The universal logic gates like NAND gate and NOR gate are also introduced to you. All logical gates can be designed by using universal logic … Read more

## XNOR gate circuit diagram using NAND & NOR gate

XNOR gate is another logical gate that is available in integrated circuit (IC) form. In other articles, we discussed that NAND gate and XOR gate are also available in IC form. Therefore, these types of logic gates are very much useful in advanced digital electronics. Basic logic gates (OR gate, AND gate and NOT gate), … Read more

## NOR gate truth table with 2 and 3 inputs

NOR gate is one of the universal logic gates along with the NAND gate. Do you know how to make NOR gate? How does NOR gate work? One can make a NOR gate by connecting an OR gate and a NOT gate in series. So, the main work of a NOR gate is to give … Read more

## NAND gate with 3 inputs – truth table & circuit diagram

The NAND gate is the most important logic gate in digital electronics. It is one of the universal logic gates. Because other logical gates can be designed by using NAND gates only. This gate is available in IC form. IC7400 is a popular IC that consists of 4 NAND gates. In other articles, XOR gate, … Read more

## XOR gate circuit diagram using only NAND or NOR gate

XOR gate or Exclusive OR gate is a widely used logical gate in digital electronics. It is one of the logic gates in the Computer which is available in IC form. We have discussed basic logic gates like OR gate, AND gate and NOT gate earlier in another article. XOR gate can be constructed by … Read more

## Basic logic gates with truth tables and diagrams

Logic gates are the basic building blocks of digital electronics that follow different logical operations. These gates have significant roles in the construction of logical circuits for different computations. Digital electronic devices contain integrated circuits (ICs) which are made of logical gates. In this article, we’re going to explore basic logic gates with truth tables, … Read more
