Hey geeks, welcome to the next article of this series on signals and systems. In the previous lecture, we saw the basic types of convolution and learned about convolution in MATLAB. This time, we are going to enhance some concepts about it by learning about the properties of convolution and by adding some important pieces of information about the same topic. Have a look at today’s concepts:
What are some basic properties of convolution?
What is the correlation?
Discuss some types of correlation and their implementation in MATLAB.
What is the difference between convolution and correlation?
How convolution is used in different areas of science and how different departments are using this technique to control the parameters efficiently.
The Properties of Convolution
Once you ...
Hello friends, hope you all are fine and having fun with your lives. In today's tutorial, we are gonna see Color Detection in Images using MATLAB. In the previous tutorial, I have posted about How to Detect Circles in Images using MATLAB in which we have detected objects based on their geometrical figure means either they are circle or not but today we are gonna distinguish objects based on their color i.e. whether they are red colored or green colored etc. Its a quite simple tutorial and comes in the basic category. We will first detect the color and then will create a boundary around that object and will also show its XY coordinates as well.
Image processing is an important tool of MATLAB. We can quite easily do the image processing in it using ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about how to convolve the signals using an amazing software tool, MATLAB. MATLAB is an efficient tool for signal processing. MATLAB basically works on matrices. First of all I would like to tell you a bit about the convolution. In engineering terms, convolution describes the output of the Linear Time Invariant (LTI) systems.
Convolution is basically an integral which tells us about the overlapping of one function as it is shifted over another function. Convolution and cross correlation are similar. It has a wide range of applications e.g. computer vision, probability, statistics, engineering, differential equations, signal processing etc. ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a project named as DTMF Decoder using MATLAB. In this project, I have designed a keypad in MATLAB using the GUI functionality of MATLAB. After designing the keypad, I have assigned a tune to each of these buttons. Obviously the tune attached to each button is different and when we press any of these buttons, then the MATLAB recognizes the respective button.
This project is designed in MATLAB and I have tested it on MATLAB 2009 and MATLAB 2014 and it works fine on both of them. Code is given below in this tutorial for download. f you got problem in it then ask in comments and I will try to resolve them. So, let's get started with DTMF decoder in MATLAB.

Hello friends, I hope you all are fine and having fun with your lives. Today, I am going to show you Color Detection in MATLAB Live Video. In this project I am gonna take a live video feed from a camera and then will detect a specific color in that video feed. I have posted a project before in which I have done the same Color Detection in Images using MATLAB but that color detection was for images but in today's post I am gonna do the color detection in MATLAB for live video feed.
I have designed this project in MATLAB 2009 and have also tested it on MATLAB 2015 and it works fine. So, I think it will work on any version of MATLAB. You must have the image processing toolbox in your MATLAB. If you got any questions then ask in comments and I will t ...
Hello friends, hope you all are fine and enjoying good health. In today's tutorial, I am going to share How to find Roots of Quadratic Equations in MATLAB. It's quite a quick tutorial in which I will give you the code and will explain it a little. Benefit of this project is that when you are learning MATLAB then you must design such small codes so that you know more about the behavior of MATLAB.
Today two of my juniors came to me for a simple MATLAB term project. It's quite an easy project but i thought to share it for those students who are dealing with basics of MATLAB. Mostly such projects are offered to students in first or second semester when they have very basic knowledge of MATLAB coding and they feel helpless while solving such problems a ...
Hey readers, welcome to another interesting lecture of this series in which we are studying signals and systems. In the present lectures, we are learning the details about the responses of LTI systems, and today, you are going to learn the step response. We also talked about the impulse response and frequency response, and therefore, this lecture will be easy for you to understand because it is, somehow, related to the impulse response. If you are new to this concept, do not worry because there will be a revision of important points side by side. Have a look at the list of today’s concepts:
What is an LTI system?
How do you define the step response of an LTI system?
What is the code to run the step response of signal in MATLAB using different functions?
How can you find the detail of t ...
Hello friends! I hope you all will be absolutely fine and having fun. Today, I am going to tell you guys that how to design a simple algorithm for DC Motor Speed Control in MATLAB by simply sending different commands to the serial port from Matlab to Arduino. In my previous tutorials, DC Motor Direction Control using Arduino, we have seen the direction control of DC Motor via Arduino. So, I would suggest you to first have a look at that tutorial before reading this one. Moreover, you should also have a look at DC Motor Direction Control in Matlab and DC Motor Speed Control using Arduino in which I have discussed in detailed about how to make simple and easy programs to control the direction of DC motor in both clockwise and anti clockwise directi ...
Hello learners. Welcome to The Engineering Projects. We all know that matrices have been used in the engineering field for a long time, and they have a vital role in the calculation of different data. Therefore, we are learning about some very special kinds of matrices that are usually introduced to engineers at a higher level. Till now, we have seen some general operations on matrices and also examined the special kinds of matrices. Yet, today, we are moving a step forward and learning about some complex types of matrices that require strong basic concepts. So, have a glimpse at the topics that you are going to learn, and then, we’ll start practicing.
What is a matrix?
What are the different types of matrices that are less common?
How can we implement some interesting commands in MAT ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Generating Simple Signal in MATLAB. Signals are of great importance in our daily life. The signals are basically the graphical display of the analog values. We can estimate the severity level by the shape of the signals. The signals have a very wide range of applications in our daily lives. If we observe the shape of the AC voltages of 220V that is supplied in our homes, it is a sinusoidal signal. So, its an application of the signals.
Signals also play a vital role in the medical field. While performing ECG and EEG tests in hospitals, doctors visualize the signals displayed on the screen and they can estimate the severity of the ...
