Electronics Engineering

gigahertz is the processing speed of your CPU(eg. 1.8GHz,2.8Ghz etc).It's the speed at which your processor runs. Gigabytes is the unit in which data(any data)in your RAM,HardDisk,Memory card or any other storage device can be stored is measured.simply,Its the unit to measure the data storage capacity.Eg- 2GB RAM,160GB hard disk etc..

A register is temporary memory which can store single bit of data....

It is a field of engineering in which we learn about the electronic component.This is the one of the branch in which we can implement our ideas and theory in developing of new electronic circuits or improving existing circuits. generally these circuits has use in communication for example mobile communication,optical fibre etc.

A journalist does not use any interviews or direct quotes in his or her report.

You can use more than one type of voltage divider in it. It can sometimes get mixed signals with all the things going on.

A scope is nothing else then a display instrument it will amplify and display a signal on a CRT for visual analysis

What is piezoelectric effect. Every day use of this phenomena is used in load cells. Load cells are used on large weigh scales for trucks and large bin scales where materials need to be weighed. The signals from the cells are calibrated to compensate for the weight of the scale so that the scale can be zeroed out. The cell signal, because it is very small, is sent to an amplifier head where is can be read by the operator in units of weight. The head unit can be set to read in metric or imperial weights. Advantages. As explained in your above question on weigh scales the load cells do away with all the mechanical linkages that the old systems had to use. These linkages were always prone to mechanical damage where as the load cells are self contained sealed units. There are four units per scale, one under each corner. I brought my two answers together to make more sense

It is television or video that gives its viewers a perception of depth. That is, a viewer can feel the depth of different objects while watching TV. The same perception of depth was possible earlier with Stereoscopic TV.

This perception of depth is given to the viewers by providing slightly different views of the same scene, to each eye of a user. By analysing the differences between these two images, the human brain is able to distinguish objects at different depths.

In stereoscopic TV, all the viewers of the scene will see the same view. This is similar to the present IMAX cinemas, which shows 3D movies. The difference between 3D TV and stereoscopic TV is that, different views will see different views of the same scene. For example, in a future cinemas the displays 3D movies with this technology, the viewers will see different views of the scene, depending upon the place they sit, in the cinema.

Of course, you still need to wear the special kind of 3D glasses because the technology that would let us see in 3D is still in the laboratories. However, these are not the same kind of glasses you get given in the cinema, the 3D glasses you use to watch 3D television are a special kind called Active Shutter Glasses.

A demultiplexer is a circuit. It has one input but more than one output. A demultiplexer gives binary information from one end to another. It is used to connect a single source to many destinations.

Exclusive Or means "one and only one of many", so the truth table of a 3 input XOR gate would be

000 0

001 1

010 1

011 0

100 1

101 0

110 0

111 0 ... or 111 1 ... see note

Many references say that 3 input XOR gate's output should be 1 when the no of 1s in inputs is Odd, and 0 otherwise. So in the given truth table, when the input is 111 output must be 1 , i.e. 111 1

plz note -- for 111 1 must be the optput.. i confirmed it

The microelectrode recordings are able to provide surgeons with images of specific brain structures. The advantage of using the microelectrode recording is that the structures are able to be identified in order to implant a pulse generator and affect disease symptoms that the patient has. The electrical stimulation has different effects per patient, however, the surgeons are able to learn more of the patients disease and conditions by watching these recordings.

Printed circuit board are electronic circuits created by mounting electronic components on anonconductive board, and creating conductive connections between them. The creation ofcircuit patterns is accomplished using both additive and subtractive methods. The conductivecircuit is generally copper, although aluminum, nickel, chrome, and other metals are sometimesused. There are three basic varieties of printed circuit boards: single-sided, double-sided, andmulti-layered. The spatial and density requirement, and the circuitry complexity determine thetype of board produced. Printed circuit boards are employed in the manufacturing of businessmachines and computers, as well as communication, control, and home entertainment equip-ment.

Variable resistor is an resistor that can change its resistance manually, by rotating a handle or a screw.

Depends on the voltage. If you are running off 120 VAC, a 0.5 horsepower motor would draw 3.1 A.

If each battery is identical, yes.

peak value =rms value*1.414 =220*1.414 =311v

hey dear, in p-n junction p-type material has more positive charged called holes and n-side having e-in majority... when we apply negative biasing then negative terminal is connected to p terminal then holes are attracted by negative terminal and e's are attracted by positive terminals.....and minority carries are forced towards junction, then at junction electron and hole pair generation occurs. after this at junction charge is accumulated by attraction and junction is get wider by a small amount that is called as depletion layer...... now you can understand how depletion layer is created..

I am not exactly sure why it is said it can't be used, I myslef was searching for an answer when I came across this, I have a general idea about this, why I would like to share.

There can be two possible reasons.

1. The inductor produces a back-emf which opposes any change in current, but in the output of a HWR, the decrease in current and a no current state predominates a increase in current, so the inductor will naturally oppose a increase in current, which will mean a low dc voltage is obtained. [i.e. lower than the peak value]

2. The reactance of inductor increases with increase in frequency, the output frequency of a HWR is half that of a FWR. Thus filtering of higher harmonic waves is favoured.

there are different network media,fiber,copper cable etc.to make communication in different media,need the media converter,for example,fiber media converter making the copper ethernet over fiber transmission,E1/ethernet converter making the ethernet over E1 conversion.

It is much easier to build a satellite transponder using different frequencies for the two directions (frequency division duplex, FDD). A single frequency (time division duplex, TDD) satellite link is possible, but then all earth terminal must be carefully synchronized. The satellite transponder and the earth terminals would be more expensive, the whole network would be more complex and less reliable. There is also a historical reason. Frequency bands were allocated decades ago and changing them would be very difficult. FDD and TDD terminals cannot coexist in the same geographical area.

voltage = current x resistance, so:

voltage = 200 x 0.001 = 0.2 volts
