A number is a method used for representing an arithmetic value, measure, or count, of a physical quantity. A number system is defined as a method of naming and representing numbers. The concept of number system helps in defining the rules associated with the numbers and different operations on numbers. ... Read More

In this tutorial, we will discuss the realization of an inverter (NOT gate) with a transistor. But before that let's have a look into the basics of inverter or NOT gate. What is an Inverter (NOT Gate)? An inverter is a single input and single output logic gate that toggles ... Read More

In digital electronics, a subtractor is a combinational logic circuit that performs the subtraction of two binary numbers. However, the subtraction of binary number can be performed using adder circuits by taking 1s or 2s compliments. But, we may also realize a dedicate circuit to perform the subtraction of two ...

In digital electronics, a logic or logic function is one that follows the rules that governs a logical statement. Logics are implemented by using switching networks, where a switching network is one that is designed by interconnecting a finite number of switches. Example − Let "𝒚" is a logic function, ...

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
