OR AND NOT gate using NAND gates |circuit diagram

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

XNOR gate circuit diagram using NAND & NOR gate

XNOR gate is another logic gate which is available in integrated circuit (IC) form. In another article, 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 gates can be designed by using NAND gates only. In other articles, XOR gate, XNOR gate and basic logic gates are designed by using NAND gates. A NAND gate can have infinite number of … Read more

p type semiconductor material – formation, properties

Earlier we have written on intrinsic and extrinsic semiconductors. There are two types of extrinsic semiconductors – n-type and p-type. We already have discussed n type semiconductor materials in another article. In this article, we are going to discuss the p type semiconductor material, its formation, properties, examples and uses. One can differentiate the n-type … Read more

n type semiconductor material – formation, properties

Impurity mixed semiconductors are known as the extrinsic semiconductors. Now, there are two types of extrinsic semiconductors. These are n type and p type semiconductors. They have different properties and the ways of formation are also different. We already have discussed p type semiconductors in another article. In this article, we are going to discuss … Read more

Formula for impedance in electronics (RLC & LC circuit)

Impedance is a frequently used word in electronics and physics. We already have discussed the resistance of a conductor in another article. Impedance is almost the same as the resistance. But there are some differences in presentation of impedance. In this article, we are going to discuss the definition, units and formula for impedance in … 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
