What is Multiplexing? Multiplexing is the process of combining one or more signals and transmitting on a single channel. In analog communication systems, a communication channel is a scarce quantity, which must be properly used. For cost-effective and efficient use of a channel, the concept of Multiplexing is very useful as it allows multiple users to share a single channel in a logical way. The three common types of Multiplexing approaches are:...

Now, doing such heavy tasks on a computer makes it hungry for power, and this is where the question arises – how much electricity does your PC consume. Furthermore, how can one measure the power that their computer draws? We have solutions for these questions and we will discuss why you need to measure your PC’s power consumption in the first place. So, we suggest you read on to get the most out of this article....

In addition to the reduction of voltage and current levels, these transformers isolate the measuring or protective circuit from the main circuit which is operating at high power levels. The current transformers reduce the level of current to the instrument or relay operating range, whereas potential transformers transforms the high voltage to a circuit operating low voltage. In this article we are going to discuss in detail about the potential transformers....

IMPORTANT NOTE: All the installation steps that I presented here are for Windows Operating System. If you are interested in learning the procedure for other operating systems like macOS and Linux, then I will try to add them.

Overview Interfacing L298N Motor Driver Module with Raspberry Pi will allow us to control a DC Motor (in fact, you can control two DC Motors). When I say control a DC Motor, I mean you can start a motor, stop it, make it rotate in forward direction, backward directions, increase the speed of rotation and also decrease the speed. For this, I’ll be using the L298N Motor Driver Module. If you remember, I have already made a project on CONTROLLING A DC MOTOR WITH RASPBERRY PI using L293D Motor Driver....

If you’re completely clueless about what the problem is or where to begin, don’t worry. This detailed guide will help you in the whole process. Let us begin by knowing what problem you’re actually facing. The Actual Problem The motherboard is the central hub for all the circuits. This is why even a little error can cause chaos to the whole machine. However, the motherboard is also equipped with powerful troubleshooting capabilities to eradicate every possible threat....

We have seen many types of Robotic Vehicles like Line Follower Robot, Bluetooth Controlled Robot, DTMF Controlled Robot, Gesture Controlled Robot, etc. but what make the RF Controlled Robot a unique project is it doesn’t use programming or a Microcontroller to control the robot and the range between the transmitter (remote control) and receiver (robot) can be significantly larger than other types. NOTE: Even a DTMF based Robotic Vehicle can be implemented without a Microcontroller....

Logitech was also in the news for the same type of device for iPhone. The idea and design was almost the same but the price of the that device was too high. This Samsung Gamepad will be available for the Indian Users at the price of 4,999 INR. Now, as per its compatibility it says that the device should be operating on Android v4.1, so though we have not used this device but we can infer that it can run on any device with this OS and it is not bound only to the Samsung Smartphone....

Whether in an IT position or managing social media for any company, paying attention to how the service functions is imperative. This will help you understand how to access data through network applications. Once you understand a server’s fundamental working, you can utilize its capabilities through virtual cloud computing platforms or a local network. With proper server maintenance, you can stay assured that the server will keep running and not show any unexpected errors....

Introduction The Silicon Controlled Rectifier (SCR) is the most important and mostly used member of the thyristor family. SCR can be used for different applications like rectification, regulation of power and inversion, etc. Like a diode, SCR is a unidirectional device that allows the current in one direction and opposes in another direction. SCR is a three terminal device; anode, cathode and gate as shown in figure. SCR has built in feature to turn ON or OFF and its switching is controlled by biasing conditions and gate input terminal....

Now with this technology information, you can start your own Solar inverter production plant with reasonable expenditure. All you have to do is purchasing good technology from the right person. What are Lacking in Current Solar Inverters? Current Solar inverters will just work as normal inverters. Only the difference between solar inverter and normal inverters is “Normal inverters run with power backup and Solar inverters run with Solar power”. Few solar inverters with better technology will charge the battery with power as well as solar panels....

Overview of Semiconductor Memory The first important question is what exactly is Memory in microprocessor systems? Memory is a device or system that has the ability to store digital information (either temporarily or permanently). In the early days of computing, engineers used magnetic tapes and discs to store information. The polarities of the magnetic field (north and south) on a circular substrate represent the digital logic values (0 and 1). But the technological developments in semiconductor design and manufacturing gave rise to Semiconductor Memory....
