Decoupling Capacitor Decoupling capacitors are mainly used to suppress high-frequency noise in the power supply signals. It takes small ripples, which could be harmful to the delicate ICs. It is also help in providing right amount of voltage supply to the circuit. If ever the power supply may drop temporarily its voltage which is a common thing, decoupling capacitor supply power briefly power to the circuit. That’s why such capacitors are known as bypass capacitors. As they act as the power supply
The Power of Ambition Throughout history, human beings have always felt the drive to achieve some form of success. One driving force behind our actions is our ambition, the strong desire to do or to achieve something. Ambition is an extremely powerful force and it controls the minds of billions of people by influencing them on every decision they make. On the other hand, human conscience, although it distinguishes right versus wrong, simply does not have the power to impact our actions or decisions
Jenna Wortham’s “Turn Off the Phone (And the Tension)”, most definitely brings the question, “what am I doing?” to mind. This article explains Wortham’s deep opinion on electronic use, and its affects on today’s society. Wortham’s article mentions the idea of going “screenless”, which is removing yourself from your phone or any other device to reconnect with what you’ve been missing in the world. I agree that this strategy is beneficial to those that are attached to their screens. Even though going
Semiconductor Devices Power electronics refers to control and conversion of electrical power by power semiconductor devices wherein these devices operate as switches. Advent of silicon-controlled rectifiers, abbreviated as SCRs, led to the development of a new area of application called the power electronics. Prior to the introduction of SCRs, mercury-arc rectifiers were used for controlling electrical power, but such rectifier circuits were part of industrial electronics and the scope for applications
1.2.6 HARMONIC DISTORTION Harmonics are sinusoidal component of periodic wave having an frequency that is an integral multiple of fundamental frequency. Now a day more use of power electronic switches and devices cause harmonics. Examples of harmonics producing loads are computers, adjustable speed drives, etc. Mitigation of harmonics can be done with the help of passive filters or active filters. Hybrid of active and passive filters also solves problems of harmonics. Figure 1.5 Distorted Current
Incredible advancements in personal electronics and social media over recent decades have led to people today being more connected to one another than ever before, with a wide array of communication mediums available. However, people are more lonely and distant (more socially isolated) in their “unplugged lives”, according to Massachusetts Institute of Technology social psychologist Sherry Turkle, PhD. Webster’s dictionary defines isolation as “the state of being in a place or situation that is
Electronic Payment System I. Introduction With the continuing rapid growth of E-commerce, transactions on the Internet have been increasing exponentially. And such transactions require some reliable and secure payment systems. In fact, one of the key factors in the success of E-commerce is the development of convenient, reliable and secure electronic payment system. To understand the issues and current activities regarding the development of electronic payment system, I discuss the
technological development has increased the demand for compact and reliable electronic devices. Compact sized products with improved connectivity coupled with high speed will likely emerge winners. Connectors are an integral part of such devices. The key drivers of the connector industry are growing 3C applications (computing, communication, and consumer electronics), miniaturization of electronic devices, and increasing electronic content in devices. The growing market in Asia-Pacific According to Bishop
self evaluation that I have decided to pursue my self graduate studies in Electrical & Electronics Engineering leading to a doctorate. This is a decision followed naturally after carefully considering my ultimate background, the area of my interest, and my ultimate professional ambition, which is to pursue a research career, either as a teaching faculty member or a R & D department of industry. i have come to terms with the fact that there is an enormous proportion of subject to be assimilated, therefore

Many experiments have been taken to compare just how much different Tech Babies are to other generations, such as the Baby Boomer Generation. Problematic habits that negatively affect this generation's children’s physically, mentally, and socially. I believe the electronics have become a negative influence on children

Electronic Arts and the Global Video Game Industry Demographic trends Gaming has become an important part of growing up for people who were born in the last 25 years. Approximately 3.9 - 4.7% of total world population (250 to 300 million people) is ¡§very active¡¨ or a ¡§frequent¡¨ player of video games or at least owns the necessary equipment. This target group spends five or more hours a week playing video games. The United States is the largest video game market in the world with about
Medicine and electronics are rapidly becoming a common partnership. Electronics and medicine has been around for over a hundred years. This application can be seen in early X-ray machines, as well as early doctors and healers who felt that electricity possessed something special that assisted the healing process of many illnesses and injuries. But it has not been the last forty to fifty years that the development and refinement of electricity as medical agent has occurred. Today the medical field
Game console is a term use to describe an electronic devices that is designed to play games on the screen of the television which it is connected. A console, also known as terminal is a basic computer connected to another computer, server or mainframe. Its function is to maintain the status of the network or computer. In some programs, console allows developers or advanced user to access the special features to issue command by pressing the tilde key when the program running. In Local Area Network(LAN)
technician did, it also shows the cycle time which is a metric tool that measures the number of minutes that it takes to perform one action, for each activity. The report is sent to all the technicians so that they can see their own performances. His long-term assignment would be to do a yearly review with each technician. The review will reflect what the technician did all year long and how the technician performed all year long. Nielsen is worldwide, so his team handles repairing the equipment of South
uncomfortable asking in class. If a teacher uses a term they don’t understand, they can find the answer discretely, and without interrupting the class. Another argument made by this group would be that social learning is a great way for students to share information, thoughts and ideas on a subject. Students who may be quiet or shy in a classroom, may blossom and flourish when planted in a social learning situation made possible by digital devices. Electronic devices in the classroom can enhance the learning
In 2005, a medical term for some of these problems was made. It was called computer vision syndrome, or CVS for short. About 90% of the 70 million American workers that use computers daily for over three hours experience CVS in some form said the Survey of Ophthalmology,

Introduction: I chose this topic; because I thought it would be fun to make a four-way switch that turns on the same light. I got the idea to make one when I went online to search for the perfect project idea. I found information about a three way light switch and decided that this is what I want to do, but to make it more difficult I decided to create a four way light switch instead. It sounds like the perfect experiment to try. I felt that if I did this project I would learn more about electricity
