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