OR AND & NOT gates using universal NAND gate

Basic logic gates like OR gate, AND gate and NOT gate are already discuused in another article. Again, we know that universal logic gates like NAND gate and NOR gate can be used to implement all other logic gates including XOR gate and XNOR gate. This article shows the Implemention methods of OR gate, AND … Read more

XNOR gate using NAND & NOR gate

XNOR gate is one of the logic gates available in integrated circuit (IC) form. Its full name is Exclusive NOR gate. It is different from Basic logic gates (OR gate, AND gate and NOT gate) and universal logic gates (NAND gate and NOR gate). In this article, we are going to discuss the logic circuit … 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 be used to represent the Boolean equation both in sum of products (SOP) form and product of sum (POS) form. There are two ways to simplify Boolean … Read more

Rules of Boolean algebra for simplification

Boolean algebra is the mathematical reasoning for simplification of binary expressions. It is completely different from the conventional general algebra. Boolean algebra deals with the binary bits only which is the arithmatic method of computers. There are different laws of Boolean algebra that are used to simplify Boolean expressions. In this article, we are going … Read more

NOR gate truth table and circuit diagram with 3 inputs

NOR gate is one of the universal logic gates other than NAND gate. NOR gate contains an OR gate and a NOT gate in series.This suggests that a NOR gate can give the inverted output of an OR gate. In this article, we are going to discuss the circuit diagram, Boolean expression and truth table … Read more

NAND Gate Truth Table and Circuit diagram with 3 inputs

NAND gate is the most important logic gate in digital electronics and integrated circuits. IC7400 is a popular IC that consists of 4 NAND gates. The biggest importance of NAND gate is that it is one of the universal logic gates using which other logic gates can be implemented. Construction of basic logic gates using … 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 provide electronic data to a computer by using input devices and the output data can be read by using output devices. Memory units store the data in the computer. In other articles, we have discussed Memory units … Read more

XOR gate circuit diagram using NAND & NOR gates only

XOR gate or Exclusive OR gate is a widely used logic gate in digital electronics that is available in IC form. XOR gate can be constructed using basic logic gates, NAND gates and NOR gates separately. Again, there can be different combinations in the same group of design. We discussed basic logic gates like OR … Read more

All Basic Logic Gates – AND OR NOT gates

Logic gates are the basic components of digital circuits that operates following Boolean algebra. These gates have significant roles in construction of integrated circuits (ICs). There are total seven logic gates in digital electronics. OR gate, AND gate and NOT gate are the three basic logic gates among those. NAND gate and NOR gate are … Read more
