PROJECT IN T.L.E Electronic Components Diodes a diode is a two-terminal electronic component with asymmetric conductance‚ it has low (ideally zero) resistance to current flow in one direction‚ and high (ideally infinite) resistance in the other. A semiconductor diode‚ the most common type today‚ is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. A vacuum tube diode has two electrodes‚ a plate (anode)

SEMICONDUCTORS ELTE 1403 Forward biased diode: cathode anode Varactor is a silicon diode optimized for its variable capacitance when reversedbiased. Used for tuning frequencydependent equipment. Zener Diode is designed to operate in the breakdown region; used for voltage regulation. Varactor Zener N + P electron flow depletion layer An ideal diode acts like a closed switch when forward biased and an open switch when reverse biased. 1st approximation calculations assume

INTRODUCTION The electronics distribution industry is inherently a volatile one because it is based on technologies that are constantly evolving and improving as time passes. The industry has already survived three major technological revolutions and can probably be expecting another one in its long-term future. These "revolutions" usually concern the refinement or replacement of a component that is fundamental to all electronic circuitry. While demand for related component parts remains relatively

Digital electronics‚ or digital (electronic) circuits‚ represent signals by discrete bands ofanalog levels‚ rather than by a continuous range. All levels within a band represent the same signal state. Relatively small changes to the analog signal levels due to manufacturing tolerance‚ signal attenuation or parasitic noise do not leave the discrete envelope‚ and as a result are ignored by signal state sensing circuitry. In most cases the number of these states is two‚ and they are represented by

ADVANTAGES AND DISADVANTAGES OF ELECTRONIC MEDIA: Electronic Media is a rich resource of services‚ supplies‚ creative and innovative solutions to everyday domestic and professional demands. We are living in the era of electronic media. None can avoid and escape from it. It is prevailing profound effects on advertisement‚ education‚ information‚ politics and other social activities.

It has opened up our ability to communicate over vast distances at near light speed. We now have many more ways in which to communicate in synchronous time with people at distances. Our asynchronous communication (like message boards and social networking) can now involve many more people than with non-electronic media. Another advantage to electronic media communication

Unfortunately‚ the consequences of one particular common element of the electronic mass media has a particularly detrimental effect on children’s well being. Research evidence has accumulated over the past half-century that exposure to violence on television‚ movies‚ and most recently in video games increases the risk of violent
