When a Boolean expression is represented as a product of sum terms, it is called POS (Product of Sums) form. In POS form, each sum term of the expression may not contain all the variables. On the other hand, when the Boolean expression is represented as a product of sum ... Read More

When a logical expression or Boolean function is expressed as a sum of minterms or as a product of maxterms, then it is called the canonical form of the expression or function. A canonical form of the Boolean expression is also known as standards form, i.e. Standard Sum of Products ... Read More

K-Map or Karnaugh Map is a simplification technique used to minimize a given complex Boolean function. K-Map or Karnaugh Map is a graph or chart which is composed of an arrangement of adjacent cells, where each cell of the K-Map represents a particular combination of variables in either sum or ...

What is Z-Transform?The Z-transform (ZT) is a mathematical tool which is used to convert the difference equations in time domain into the algebraic equations in z-domain.The Z-transform is a very useful tool in the analysis of a linear shift invariant (LSI) system. An LSI discrete time system is represented by ... Read More

A circuit is a type of network having a closed path for the flow of either electric current or magnetic flux. A circuit mainly consists of three major parts viz. source, path or conductor and load. In simple words, the term circuit can be used to represent any fixed path ... Read More

In MATLAB, we can create different types of graphical user interface (GUI) components like Edit Fields, Hyperlinks, Buttons, and more. In this tutorial, we shall confine our attention to add a ButtonGroup in MATLAB. What is a ButtonGroup in MATLAB? MATLAB is an environment that provides an easy way of ... Read More

Let us start this tutorial with a brief discussion on "what is inverse of a square matrix" and "the significance of Cayley Hamilton theorem". What is Inverse of Square Matrix? In linear algebra, there is a fundamental concept called the inverse of a square matrix. Consider a square matrix ‘A’, ... Read More

In digital image processing, the gray level co-occurrence matrix, also known as GLCM, is a statistical method employed for holding the spatial relationship between pairs of pixels in a digital image. The gray level co-occurrence is a method of representing the way in which different combinations of pixel intensities are ... Read More

MATLAB is a great tool to process matrices. It provides a large number built-in functions and processing methods that we can use to manipulate our matrices just by writing a small piece of MATLAB codes. Such an operation that we can perform on matrices in MATLAB is random shuffling of ... Read More

MATLAB is an object-oriented programming (OOP) language that allows us to create objects and define their behavior. In MATLAB, there is a data type called 'Handle' which is used to point an object. Handles in MATLAB also allows us to pass a function as an input argument of some ... Read More
