NOT AND OR gate using NAND gate – circuit diagram

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

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 consists of 4 NAND gates. In other articles, XOR gate, XNOR 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 Computer which is available in IC form. We have discussed basic logic gates like OR gate, AND gate and NOT gate earlier in other articles. XOR gate can be constructed by using … Read more

Basic logic gates with truth tables & diagram | 2 & 3 input

In digital electronics, logic gates have significant roles to construct logic circuits in computer. Logical gates are the basic building block of digital electronics. Most of the digital devices contain integrated circuits (ICs) in it which are made of the logical gates. In this article, we are going to discuss all the basic logic gates … Read more
