Difference between Motor and Generator
The conversion of mechanical energy into electrical energy and electrical energy into mechanical energy is a necessary process in the industries as well as in our daily life. Electrical machines are used for the conversion of electrical energy into mechanical energy and mechanical energy into electrical energy.Depending upon the type of electromechanical energy conversion, the electrical machines are divided in two types as, Electric MotorElectric GeneratorIn this article, we will explain the key differences between electric motor and electric generator. We also added a brief description of the motor and generator for your reference.What is an Electric Motor?An electromechanical energy ...
Read MoreDifference between Assembly Language and High-level Language
A computer is simply a machine and hence it cannot perform any task itself. Therefore, to make a computer functional different coding languages are developed, which are known as programming languages. A computer programming language is a language in which the codes are written to instruct the computer to perform tasks. Computer programming languages are broadly classified into the following three main categories − Machine Language Assembly Language High-level Language Read this article to get an overview of assembly language and high-level languages, and how they are different from each other. What is Assembly Language? Assembly language is ...
Read MoreBiCMOS Technology: Fabrication Process and Applications
BiCMOS stands for Bipolar Complementary Metal-Oxide Semiconductor. BiCMOS technology is an integration technology that combines bipolar and CMOS (Complementary Metal Oxide Semiconductor) devices on a single chip. This technology is primarily used to combine the features of analog and digital circuits in a single IC chip. In this article, we will discuss BiCMOS technology, its definition, fabrication process, advantages, disadvantages, and applications. Before discussing the BiCMOS technology, let us first get an overview of bipolar technology and CMOS technology individually. What is Bipolar Technology? A semiconductor technology in which BJTs (Bipolar Junction Transistors) are used as the fundamental building blocks ...
Read MoreUp Sampling in Frequency Domain in MATLAB
Introduction to Up−Sampling In digital signal processing, the technique which allows to increase the sampling rate of a signal is termed as up−sampling. For a signal expressed in frequency domain, the up sampling is performed by adding zeros in the frequency domain. In digital signal processing, the up sampling in frequency domain is commonly used to interpolate or expand the bandwidth of a digital signal. In MATLAB, the up−sampling process is completed in the following three phases: Step 1 − Perform Discrete Fourier Transformation (DFT) In this phase/step, the given signal is transformed from the time domain to the frequency ...
Read MoreThresholding-Based Image Segmentation in MATLAB
In computer−based image analysis and processing, the image segmentation is an essential task. The image segmentation allows us to extract specific objects or regions from an image. In digital image processing, the most widely used image segmentation technique is the thresholding−based image segmentation. This image segmentation technique works depending on the pixel intensity values to separate different regions within an image. In this article, we will discuss learn the implementation of thresholding−based image segmentation using MATLAB programming. But before that let’s get into the basics of thresholding and its types. What is Thresholding? In digital image processing, the thresholding is ...
Read MoreHow to Convert RGB Image to YIQ Image using MATLAB?
In the field of digital image and video processing, there are two popular color spaces namely RGB and YIQ. Where, RGB stands for Red, Green, and Blue. The RGB color space is widely used for displaying digital images on display screens. This color space utilizes a combination of intensities of red, green, and blue lights. Therefore, in the RGB color space, each pixel in a digital image composed of three−color channels namely red, green, and blue. On the other hand, YIQ is another color space that is mainly employed in analog video or NTSC systems. YIQ stands for Luminance (Y), ...
Read MoreHow to Create a Dropdown Menu in MATLAB
In this article, we will learn how to create a dropdown menu/list in MATLAB. In MATLAB, a dropdown menu is a user interface (UI) component allows users to choose one the multiple options or to type as text. In MATLAB, we have a built−in function named ‘unidropdown’ that allows to create a dropdown menu. This function can have different syntaxes to create different types of dropdown menu. The most commonly used types of dropdown menu are as follows: Dropdown menu without any parameters Dropdown menu with a specific parent container Dropdown menu with a specific parent container and properties ...
Read MoreHow to Count the Number of Circles in Given Digital Image Using MATLAB?
In this article, we will learn to implement MATLAB codes to count the number of circles in a digital image. The counting the number of circles in an image is performed by using various image processing techniques like image erosion, circle detection, etc. The step−by−step procedure to count the number of circles in a digital image in MATLAB is explained below: Step (1)− Read the input image. Step (2)− Convert the input image to grayscale, if necessary. Step (3)− Create a circular or disk−shaped structuring element of a specific size for erosion of the image. Step (4)− Erode the grayscale ...
Read MoreHow to Create a GUI Button in MATLAB App?
In MATLAB App environment, we can develop a GUI (Graphical User Interface) app without having proper knowledge of coding. Therefore, MATLAB app building allows us to create professional applications without writing code, and just by drag−drop. In this article, we will discuss how to create a GUI button in a MATLAB application. The step−by−step procedure to create a GUI button in a MATLAB app is explained below. Steps to Create GUI Button in MATLAB App We can follow the following steps to create a GUI button in a MATLAB application: Step(1)– Open the MATLAB command window. Step(2)– Launch the MATLAB ...
Read MoreHow to Change the Background of an Image with Green Screen Background in MATLAB?
In this article, we learn how to change the green background of an image to some other background using MATLAB programming. The concept of changing a green screen background to another background involves the use of a technology called “chroma key”. This technology detects the absolute green color in the image and omits it from the image. Then, we can apply another image or color as the background to the image. Algorithm The step−by−step process of changing the green screen background of an image with another background in MATLAB is explained below: Step (1) − Read the input image with ...
