A logic gate is a digital electronic circuit that is used to implement different kinds of logical and comparison operations. We have several types of logic gates such as OR Gate, AND Gate, NOT Gate, NAND Gate, NOR Gate, etc. In this article, we will discuss the realization of OR ... Read More

What is Karnaugh Map? In realization of digital electronic systems, the simplification of Boolean expressions is one of the most crucial steps because it reduces the hardware complexity and cost of production. There are several tools and methods available for simplifying complex Boolean expression. K-Map or Karnaugh Map is one ... Read More

In digital electronics, there are different types of logic circuits used to perform different kinds of arithmetic operations. One of them is adder. Adder (or Binary Adder) is a combinational logic circuit that performs the addition of two or more binary numbers and gives an output sum. There are two ... Read More

In digital electronics, adders and subtractors both are the combinational logic circuits (a combinational logic circuit is one whose output depends only on the present inputs, but not on the past outputs) that can add or subtract numbers, more specifically binary numbers. Adders and subtractors are the crucial parts of ... Read More

A K-Map or Karnaugh Map is a graphical method that used for simplifying the complex algebraic expressions in Boolean functions. This method avoid the use of complex theorems and equations manipulations. A K-Map is basically a special form of a truth table that can easily map out the values of ... Read More

Let’s begin with the basic introduction of voltage regulator. A voltage regulator is an essential element of power supplies used in several electrical and electronic devices such as computers, amplifier, ... Read More

Electricity is form of energy that is obtained from other form of energy such as chemical energy, nuclear energy, heat energy, solar energy, etc. available in the nature. Electricity is the phenomenon associated with the existence and motion of the electric charge in the matter. This article is meant for ... Read More

The collection of electrons (electric charge) at a short distance away from a metal surface forming a cloud of electric charge around the metal surface is known as space charge. These electrons are emitted from the metal surface on the application of electric field. In other words, the space charge ... Read More

We have several electrical and electronic circuits that require a DC power supply to operate. But, due to some technical and economical limitations, we cannot use conventional sources of DC power such as batteries and DC generators. In this situation, we use an electronic circuit that can convert AC power ... Read More
