FM stands for Frequency Modulation, a technique used in communication systems for long distance transmission of data and information. The frequency modulation involves the alteration in the frequency of the signal so that it can be transmitted over long distances without any distortion of the information. In this tutorial, I ...

In a binary image, the interior and exterior skeletons are used to represent the essential structure of the objects and shaped within the image. In this article, I am going explain the process of finding the interior and exterior skeleton of binary image using MATLAB. Before discussing the process of ... Read More

We can use MATLAB to create a partially colored gray image, which we will discuss in this tutorial. But before that, let us first get an overview of what a partially colored gray image is used for. What is a Partially Colored Gray Image? A digital image in which some ... Read More

In digital image processing, histogram equalization is a common method of improving the visual quality of a digital image. We can perform histogram equalization of a digital image using MATLAB. We have a built-in function "histeq" in MATLAB to perform this task. However, we can also perform histogram equalization without ... Read More

In interpolation, filtering after upsampling is an important step to avoid the aliasing and reconstruction of a filtered signal. In MATLAB, there are various built-in functions that can be used to perform filtering after upsampling in interpolation. Before discussing the process of filtering after upsampling, let us first know about ... Read More

In digital images, the gaussian noise is a type of noise that follows a normal or Gaussian distribution. In a digital image, the gaussian noise is visualized as a random variation in pixel intensities. The estimation of gaussian noise is one of the important tasks in digital image processing utilized ... Read More

In digital image processing, denoising is a process of reducing or removing the unwanted noise from a digital image. The primary objective of this process is to enhance the visual quality of an image. Before discussing the different denoising techniques in digital image processing, let us first get an overview ...

In this article, we will discuss different types of ICs (Integrated Circuits) in electronics. As we know, the integrated circuits (ICs) are one of the crucial parts of all electronic devices and systems. Without ICs, most of the hi tech electronic devices and gadgets that we use would cease to ... Read More

Let's start this tutorial with a basic introduction of 8:1 multiplexer before moving on to cover how a three variable logic function can be implemented using an 8:1 multiplexer. Introduction to 8:1 Multiplexer A multiplexer (or MUX) is a digital logic circuit that accepts multiple data inputs and allows only ... Read More

Simplification is an approach in which a Boolean expression is minimized or reduced into an equivalent expression by using some Boolean identities. Boolean algebra is a mathematic applied to binary number system. It was developed by George Boole, an English mathematician, to simplify complex logical operation to their simplest form. ... Read More
