technology Punched cards and paper tape were invented to feed programs and data and to get results. Magnetic tape / magnetic drum were used as secondary memory Mainly used for scientific computations. Second Generation (Manufacturers – IBM 7030, Digital Data Corporation’s PDP 1/5/8 Honeywell 400) Transistors were used in place of vacuum tubes. (invented at AT&T Bell lab in 1947) Small in size Lesser power consumption and better

CHAPTER ONE INTRODUCTION DEFINITIONS OF SOME TERMS A DIGITAL SYSTEM is a data technology that uses discrete (discontinuous) values. By contrast, non-digital (or analog) systems represent information using a continuous function. Although digital representations are discrete, the information represented can be either discrete, such as numbers and letters or continuous, such as sounds, images, and other measurements. The word digital comes from the same source as the words digit and digitus (the

technology uses these pulse signals and apply them to the communications INTRODUCTION Nonlinear Dynamical Systems (NDS) are the mathematical formulations required to simulate the cell responses. It uses portable devices, and provide these devices with faster, better data for longer periods of time. It consumes very little power. PRINCIPLE OF CELLONICS TECHNOLOGY Cellonics - Electronic cells. It has the ability to encode, transmit and decode digital information over a variety

Audio Recording Convergence and the Digital Age Final Project Abstract With information technology advancements and a more computer savvy world, the audio recording medium and digital medium have merged, changing the sound recording industry forever. This convergence has blurred the line between professional and amateur sound recordings. Technology has made new products smaller, feature rich and more affordable where anyone can record their music and offer it

incoming signals before sending the data on to its destination. Passive hubs do nothing with the signal. Ethernet Hubs An Ethernet hub is also called a multiport repeater. A repeater is a device that amplifies a signal as it passes through it, to counteract the effects of attenuation. If, for example, you have a thin Ethernet network with a cable segment longer than the prescribed maximum of 185 meters, you can install a repeater at some point in the segment to strengthen the signals and increase

technology (IT) is a field concerned with the use of technology in managing and processing information. Information technology can be an important enabler of business success and innovation. Information technology can be composed of the Internet, a personal computer, a cell phone that can access the Web, a personal digital assistant, or presentation software. All of these technologies help to perform specific information processing tasks. There are two basic categories of information technology: hardware

OSCILLOSCOPE A mixed signal digital Oscilloscope (Figure 4.5) was used to record the signals from accelerometer, laser vibrometer, strain gage and impulse hammer. It shows the wave shape of the electric signals in time voltage scale. This allows the measurement of, for example, peak-to-peak voltage of a waveform, the frequency of periodic signals, the time between pulses, the time taken for a signal to rise to full amplitude (rise time), and relative timing of several related signals. The specifications

transferred over radio waves then back into an electronic signal in the device. A modem is a piece of equipment used to connect a user’s computer to a network. The modem is essentially a converter in that it can convert analog cables to digitals ones and vice versa. The analog signals come from a telephone wire that is inserted in the modem and the digital signals are what the computer sends out, the signals need to be converted because a digital to digital connection is not possible with a modem. There are

Automatic Number Plate Recognition (ANPR) system is an image processing technology [6]. ANPR is the extraction of vehicle number plate information from an image or a sequence of images. The extracted information can be used with or without a database in many applications, such as electronic payment systems (toll payment, parking fee payment). The quality of the acquired images is a major factor in the success of the ANPR. ANPR as a real-life application has to quickly and successfully process number
