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 everyone, I hope you all are doing great. In today's tutorial, I am going to show you the advantages of Outsourcing Software Development. If you are a software engineer and also an Entrepreneur, then you must have heard about Outsourcing. You must have a look at this outstanding tutorial because they have quite clearly answered this question Why Outsourcing Software Development?
Technologies have evolved in an amazing way to leverage people and make their lives easy. The role of Artificial Intelligence in Software Development has revolutionized this industry. Nowadays, companies that survive in the market are the ones with a better understanding of their goals and work in a strategic way. You cannot adopt old ways to run your businesse ...
Hello everyone! I hope you will be absolutely fine and having fun. Today, I am going to give an Introduction to 1N4148. It is basically a diode used for fast switching purposes. Switching diodes are usually single P-N diodes and their functionality is similar to that of normal switch.
Below a specific voltage, switching diodes i.e. 1N4148 has high resistance. Whereas as above that specific voltage they show a low resistance. It is a most commonly used diode due to its smaller size, easy availability and low cost. Good switching diode can be chosen by its maximum reverse recovery time and its power dissipation ranging from 80mW to 1kW. Switching diodes such as 1N4148, 1N4007 etc. have very wide range of applications specially in Embedded Systems ...
Hey Guys! I am back to give you a daily dose of information so you can excel and grow in your relevant field and keep coming back for what we have to offer. If you are a hobbyist or student, you require a transistor for the execution of your project every now and then.
Today, I am going to unlock the details on the Introduction to 2n4123. It is an NPN (negative-positive-negative) general purpose transistor which is mainly used for the amplification and switching purpose where collector current around 100mA is required. It is a semiconductor device mainly composed of silicon and comes with three terminals where a voltage applied to the one pair of terminals is used to control the current at the other pair of terminals.
I'll break down each and ev ...
A printed circuit board(PCB) is the most important part of an electronic device. A high-quality PCB is necessary to make a safe and durable device. PCB manufacturers should strive to maintain high quality at a low price. To achieve this goal, some matters should be taken into account.Some key factors affect the prices of PCB manufacturing and assembly. PCB price depends on size, number of layers, quantity, etc. The material that we choose for PCB also affects the cost. The PCB printing process also matters in this regard. For example, some PCB manufacturers print PCBs manually while some control the whole process with CNC machines. Manual PCB printing is cheaper than CNC machine-printed PCBs. PCB manufacturing is a complicated task that needs experience and technology. A trusted PCB partne ...
Hello everyone and welcome to this article which will be a great introduction to high-speed PCB design. For sure it is going to be a very interesting class. Let me start by posing a question; Is this something that you have ever come across in your world of PCB design? Where you spent too much time doing the schematics, selecting the right components, doing the footprint addition, generating the netlists, doing the proper layout and routing and sending the end product of your design to the manufacturer? At this level you might probably be designing standard types of PCB boards and if someone was to introduce a project that talks about signal integrity, reflections or even crosstalk, very much believe you will feel like a lost person. It might be s ...
Tablets are great devices for active and busy people. It’s a convenient device to carry with you and if you’re a business person, it can make working on the road a lot more pleasant than simply using your smartphone. However, buying a tablet isn’t necessarily easy, as you have so many options available. It can be even trickier if you are working with a specific budget – you want to make sure you get the best tablet money can buy.
They help you out, here are some tips on how to choose the best Android tablet within your budget.
Set your budget
You must start your tablet hunt by setting yourself a budget. It’s important you look at the bank account and think carefully how much you are able to and willing to spend on the new device.
In terms of the ...
The Internet of Things (IoT) philosophy may be viewed as a highly dynamic and radically dispersed networked system comprised of a huge number of identifiable smart devices. These objects may communicate and interact with one another, as well as with end-users and other network entities. As the Internet of Things era begins, the usage of small, inexpensive, and flexible computer hardware that allows end-user programming becomes more prevalent. The Raspberry Pi, a fully configurable and programmable tiny computer board, is one of them discussed in this article. Although there are certain limitations, the Raspberry Pi remains a low-cost computer that has been used effectively in a wide range of IoT vision research applications despite its few shortcomings.

Hello friends, I hope you all are doing great. In today’s tutorial, we will discuss What is Full Wave Rectifier. Transformation of alternating current into the direct current is known as rectification. This conversion can be done by using a single diode or more than one diode. The diode that used for rectification is named as a rectifier. There are 2 main categories of the rectifiers, the first one is the half-wave and the other is full-wave rectifier.
In half-wave rectification circuitry, there is only single diode is used to convert alternating current into the direct current. So it can very easily design for rectification. But it has one drawback that it converts one half of the AC wave into direct current. Due to this, there is a higher power ...
Hello friends, I hope you all are doing fine. In today's tutorial, I am going to share a new Soil Moisture Sensor Library for Proteus V2.0. You should also have a look at its previous version i.e. Soil Moisture Sensor Library for Proteus V1.0. If you have worked on the previous version, it has only one soil moisture sensor in it, while in this library, we have added three soil moisture sensors.
First, we will have a brief introduction of the Soil Moisture sensor, then we will download the zip file containing Proteus Library files of Soil Moisture Sensor and finally, we will design a small simulation using these new sensors. So, let's get started:
What is Soil Moisture Sensor?
Soil Moisture sensor is an embedded sensor, used to measure the moist ...
