Hello friends, I hope you all are having fun. In today's tutorial, we will have a look at Introduction to Polymorphism in C#. It's our 16th tutorial in C# series and polymorphism is considered as a main pillar of object oriented programming.
In our previous tutorial, we have seen a detailed Introduction to Inheritance in C# and along with it, we have also discussed How to hide a Method in Parent Class, if the same method exists in Child class. This Method Hiding is actually the basis of Polymorphism, so let's discuss it out in detail:
Introduction to Polymorphism in C#
Polymorphism in C# enables the user to invoke a Child Class Method & override the Parent Class Method, using a Parent Class Reference variable.
In our previous lecture o ...
Hello friends, hope you all are fine and enjoying life. Today's post is about removing a small error named as Recognition Failed in EasyVR, which I encountered while working with EasyVR shield with Arduino UNO. I have posted a complete project on EasyVR shield around a year ago in which I haven't mentioned this error because at that time I didn't encountered it. But today while working with EasyVR shield, I encountered this problem so I thought to share it with you guys.
EasyVR shield is a voice recognition module which is used for recognizing voices and operating accordingly. Using this module, one ca quite easily control anything using voice. In the previous project, I have controlled a robot using voice commands like when I say Forward then it ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to MMBD914. MMBD 914 is basically a switching diode. A switching diode has the functionality similar to the switch. Like an open switch, MMBD 914 has a high resistance for the particular applied voltage.
Switching diodes are usually used in different device e.g. ring modulation. The right switching diode can be chosen keeping in mind our requirements e.g. reverse recovery time, power dissipation and maximum peak current etc. I have also written an article on another switching diode, Introduction to 1N4148, and this my second article on switching diodes. MMBD-914 has a vey wide range of applications including high spee ...
What raw materials that your PCB is comprised of?When you cannot answer this question clearly, please continue reading. When you are interested in PCB raw material testing, you better keep reading. When you are in doubt about the quality of the JLCPCB board material, you must continue reading. All corporations that value products and services paramount importance. The raw material is life for a product. This is especially true for PCB production. How JLCPCB controls the level of raw materials quality? The testing videos tell the truth.
JLCPCB never take undue advantage of Non-A grade board
Global PCB raw material costs are rising, JLCPCB never takes undue advantage of Non-A grade board. Last year the whole PCB manufacturing industry faced raw mat ...
Till now, we have read about the basic concepts and functions in the signal and system, but let’s have something that is more practical and practice each and every topic thoroughly because if you have the understanding at each point, transforming will become an interesting game for you.Keep in mind, that transforms are an important topic in signal processing, but they were traditionally taught in the same way they were discovered: through calculus. This approach, however, does not reveal the true purpose of the transforms or why they are desirable. Well, let’s check the topics that we are going to learn about today:
What are transforms?
Which common transforms are used in signals and systems?
What is the Laplace transform?
How can you implement the Laplace transform in MATLAB?
What ar ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Affect of Noise on Signal in MATLAB. Noise is basically an unwanted signal that effects the normal signal. Noise the natural signal which can be removed but can be reduced to some extent. We can see a lot of examples of the signals effected by noise in our daily lives e.g. the distorted voice signal while calling, creates hearing problems, distorted TV signal makes the video invisible and the distorted AC signal can burn most of the home as well as other appliances.
In signal processing term, noise is also known as the unwanted signal which carries no useful information. To recover the original signal from the noise effected one, ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to provide a detailed discussion on Introduction to LM258. LM-258 has two internal Operational Amplifiers (Op-amps) which are frequency compensated internally. They are specially designed to perform their tasks from a single power supply source using a wide range of voltages. They can also perform different operations using split power supply. LM-258 low power supply current drain does not depend upon the magnitude of the power supply source.
LM 258 has a lot of features including high DC voltage gain, large bandwidth, different input voltage equal to power supply, large output voltage swing, common mode input voltages include ground. These were the few of m ...
Matrices are an essential topic in different fields of study, especially in mathematics, where you have a bulk of data and want to organize, relate, transfer, and perform different operations on data in a better manner. We have studied a lot of types and operations on the matrices and have worked on different types with the help of MATLAB. Today, we are here to present the applications of the matrices in different fields of study to clarify the importance of this topic. So, have a look at the list of topics we are going to learn. Yet, first of all, I am going to describe what a matrix is.
What is a Matrix?
In the fields of physics and mathematics, there is the use of different types of numbers in groups of various types. In order to organize the data into a manageable format, matrices ar ...
Hey, pupils welcome to the next session about the Fourier transform. Till now, we have learned about the basics of Fourier transform. It is always better to understand all the properties of a mathematical tool to understand its workings and characteristics. You will observe that most of its properties are similar to the topics that we have discussed before, and the reason is, that all of them are transforms, and the core objective of these transforms is the same. We have learned about the simple and easy discussion of the Fourier Transform, but when dealing with complex problems, it involves the usage of different properties so that we do not have to repeat the calculations all the time to get the required results. Have a look at what you are going to learn today:
What are the basic prope ...
Hello friends! I hope you all will be absolutely fine and having fun. Today, I am going to give you an elaboration on Introduction to 2N3772. I have already shared basic knowledge about different IC's and transistors in my previous tutorials e.g. Introduction to IRF540, BC547, MMBD914, LM339, LM224 and LM386. You must have alook at these tutorials before going into the details of this tutorials. It will be quite helpful in the better understanding of this article. 2N-3772 is basically a type of central semiconductor. It is basically a Negative Positive Negative (NPN) semiconductor. This semiconductor is designed by the process named as epitiaxial process. The main purpose behind its designing is to provide the high power based amplification proce ...
