Hello Pupils, We are learning about signals and systems, and till now we have learned some basic information regarding signals, but we know a little about systems till now. We have learned about the system in our previous lectures. To have a clear concept, we have arranged this tutorial in which we are studying the systems and their classification. Have a quick glance at today’s topics:
What is a system?
What are the various types of systems?
What is the principle of homogeneity?
What is the principle of superposition?
How can we compare each type while keeping their differences in mind?
To keep things simple, we’ll also have examples of some of these signals. Yet, the first thing that we are going to do is to revise the basic definition of the system so that we may move forward. ...
Hello friends, I hope you all are having fun. In today's tutorial, we are going to discuss How to use Arrays in C#. It's our 6th tutorial in C# series and currently we are focusing on basic concepts in C#.
Without understanding these simple concepts, we can't move forward. So, let's get started with Arrays in C#:
How to use Arrays in C# ???
An array (base type System.Array) is a collection of similar (like-typed) data types, called by a common name. Each data item is referred as an element of array and is assigned an index starting from 0.
As C# array is an object so we can find its length using member length, which is actually a count of total number of data items in that array.
Arrays are reference types and implement IEnumerable that' ...
Legacy software refers to a business operating software that has been in use for a long time. This is older system software that is still relevant and fulfills the business needs. The software is critical to the business mission and the software operates on specific hardware for this reason.
Generally, the hardware in this situation has a shorter lifespan than the software. With time, the hardware becomes harder to maintain. Such a system will either be too complex or expensive to replace. For that reason, it continues operating.
What is a Legacy System?
Legacy software and legacy hardware are often installed and maintained simultaneously within an organization. The main changes to the legacy system typically only replace the hardware. That helps ...
Printed circuit board is a very important part of electronic devices. You will find them in all electronic appliances. To make a good quality PCB, it is very important to select high-grade materials. A PCB mainly consists of a NON-conductive material. Conductive lines are etched or printed on them.
PCB materials are mainly of 3 types.
FR-4TeflonMetal
Among these 3, FR-4 is the most common. This article will discuss all that you need to know about FR4 PCB Fabrication. We will discuss all about FR4. We will focus on its advantages.FR-4 Manufacturing
PCBway Fabricaton House manufactures high-quality FR4 PCBs. They can produce these PCBs really fast. The cost is also optimum. They are capable of making multi-layered FR4 PCBs.

Hello friends, I hope you all are doing great. In today tutorial, I am going to give you a detailed Introduction to Methods in C#. It's our 12th tutorial in C# series. So far, we have covered all the basic concepts in C# and now it's time to move forward and have a look at some complex concepts.
Methods have an important role in C# programming and if you want to be an efficient programmer then you must set your method controls correctly. Some methods have secret codes in them, which you don't want to give access to your developers, then you can set it private. We will cover such things in detail later, let's first have a look at Introduction to Methods in C#:
Introduction to Methods in C#
Methods in C#, also called Functions, are extremely usef ...
Hello friends, I hope you all are doing great. Today, I am going to share Circuit Designing of LCD with Arduino in Proteus ISIS. In my previous tutorial, I have posted a tutorial on How to use Arduino Library in Proteus. Using that library, we can easily test Arduino code in Proteus to check whether its working or not. If you haven't read that post then before starting it, first read it, as without adding the arduino library we can't use Arduino in Proteus.
Coming to today's post, as we have done adding the Arduino Library in Proteus, so I thought to do some projects on it and the first one I chose is quite simple one i.e. Circuit Designing of LCD with Arduino in Proteus ISIS. So we will have a look on how to show some characters on LCD using Ardu ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge with all of guys about Introduction to IRF540. It is basically an N-Channel power Metal Oxide Silicon Field Effect Transistor (MOSFET) and operates in enhancement mode.
MOSFET is a lot sensitive in comparison to an FET (Field Effect Transistor) due to its very high input impdence. IRF540 can perform very fast switching as compared to the normal transistor. It is based on HEXFET technology and operates on the temperature ranging from -55 degrees celsius to 175 degree celsius. If we need some switching application between different signals or to perform any of amplification process, MOSFET IRF540 will be the best option in this case bec ...
Hello friends, I hope all are fine. Today, we are going to share the 3rd chapter of Section-III in our Raspberry Pi Programming Course. In our previous lecture, we interfaced the Soil Moisture Sensor with Raspberry Pi 4. Today, we are going to Interface the Infrared(IR) sensor with RPi4. IR Sensor is typically employed for the presence/motion detection of objects in the immediate area. With their low power consumption, straightforward design, and user-friendly features, IR sensors are a popular choice for detection purposes. Infrared(IR) impulses are invisible to the naked eye and lie between the visible and microwave parts of the electromagnetic spectrum. So let's get started:
Components Required
To learn how an IR sensor detects the existence o ...
Hello everyone, I hope you all are doing great. In today's tutorial, I am going to give you a detailed Introduction to Arduino YUN, and we will also have a look at its basic functionalities. Arduino YUN is a latest microcontroller board, manufactured by Arduino. It's the most advanced and highly stylish arduino board. The beauty of Arduino YUN lies in having two on board processors, which I haven't seen yet in any other Microcontroller board. One of them is simple Arduino processor which is similar to that of Arduino Leonardo while the second processor is Atheros AR9331. Atheros supports Linux server, which is the new thing in Arduino YUN. Because of these two processors, one now can do anything in the world of automation as well as web servers. ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a detailed Introduction to Structures in C#. It's our 17th tutorial in C# series. Structures are quite similar to classes but have few differences as well, which we will discuss today.
We have discussed C# Classes in 13th lecture, so you must read it once as we will use that knowledge in today's lecture as well. So, let's get started with Introduction to Structures in C#:
Introduction to Structures in C#
Structure in C# is a value type data type, created by using keyword struct, and can have fields, methods, properties, operators etc. just as in C# Classes.
Main difference between C# Class & Structure is that C# Class is a Reference Type Date type while C# St ...
