The Integrated Circuit: The Evolution of an Electronic Miracle The microprocessor evolved over the course of many years of research‚ and people all over the world enjoy the benefits of this electronic miracle. It is difficult to think of anything that has affected modern life more than this invention. Cellular phones‚ wristwatches‚ calculators‚ automobiles‚ stereos‚ televisions‚ and computers are just a few of the thousands of electronic devices that have a microchip at the heart of its operation

Gyan Vihar University‚ Jaipur‚ India Continues growth of electrical energy demand is resulting in a corresponding increase in the short circuit in power system‚ which results in voltage sag problems and threat to power quality in the system. Several solutions have been implemented‚ including the use of Fault Current Limiter (FCL)‚ in order to reduce circuit breakers rated capacity and to limit the electromagnetic stress in associated equipment. This paper presents a study of the impact of fault

that have time to check filter theory as shown in the college communications textbook. The pre-engineers are going to build a Narrow Band Pass Filter to compare theory with designed circuit behavior. By doing this the students will be able to better understand the theory based calculations and build hard wired circuits. When designing a band-pass filter‚ the parameters of interest are the gain at the mid frequency and the quality factor which represents the quality of the band-pass filter. A band-pass

In this project‚ there are three type of passive filters that will be built on printed circuit board (PCB)‚ to investigate the different result when applied as real circuit with the software design simulate as in theory. There are low pass filter‚ high pass filter and band pass filter. The design would be in second order Butterworth low pass‚ high pass and band pass filter using

think about the people that made this technology possible. Throughout history‚ there have been only a handful of persons that have truly altered the way in which a society operates and lives. Jack Kilby ’s invention of the monolithic integrated circuit‚ or better known as the microchip‚ gave birth to a new technological field of modern microelectronics. His ingenious work at Texas Instruments over forty-five years ago‚ was a breakthrough that has led to the "sophisticated high-speed computers and
