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 which 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 type of logic gates are very much useful in advanced digital electronics. Basic logic gates (OR gate, AND gate and NOT … Read more

Karnaugh map for simplification of Boolean expression

Karnaugh map is a very useful tool for simplification of Boolean expression in digital electronics. The other name of Karnaugh map is K-map or K map. It can represent the Boolean equation both in sum of products (SOP) form and product of sum (POS) form. There are two ways to simplify Boolean expressions. One is … Read more

Rules of Boolean algebra for simplification

Boolean algebra is a very useful method for simplification of binary expressions. There is no connection between the general algebra we know and the Boolean algebra. Boolean algebra deals with the binary bits only. There are different laws of Boolean algebra to simplify the Boolean expressions. In this article, we are going to discuss all … 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. Now, 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 the inverted … 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

Examples of input devices in computer with images

The components used in a computer are Input devices, Output devices, a CPU, and Memory units. We can give a data to a computer by using input devices, the output data can be read by using output devices and the memory units store the data in the computer. In other articles, we have discussed Memory … 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 table & diagram (2 & 3 inputs)

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
