Consider a periodic function, generally defined by

f(x+t) = f(x) for some t.

Any periodic function can be written as an infinite sum of sines and cosines. This is called a Fourier series.

in the negative biasing it gives the constant voltage irrespective of limited current.......the voltage it provides in the negative biasing is known as 'zener voltage' due to this property zener voltage is used as voltage regulator........voltage regulator is a circuit which gives constant output even the input is changing.

Yes, bullet trains have wheels. They run on rails, just as conventional railroad locomotives and cars do. The trains that operate by magnetic levitation, the so-called MagLev trains, do not have wheels as they ride on a magnetic cushion.

Well it all depends on the company with which the game tester is working. Some major companies have consantly new game which they are developing and therefore they would need their testers to be able to work in a constant way. If you are referring to the number of hours that a tester would work for during a normal typical day, some tester work for around six hours a day whilst some do up to ten. If you would like more information, it is readily available at www.GameTesterWork.info

Wind power is another name for wind energy.

Aerogel is the best insulator [.004 W /( MK)] and diamond or diamond-chickenwire-tube (carbon nanotubes) are the best [2320 W/(MK)].

A multimeter when used on voltage, has a very high resistance/impedance to limit the current flowing through it. However when you set it to read current, it has a very small resistance to encourage the current to flow through the metre so can be measured. So ig you put a multimeter across a voltage source (in parrallel) when its set to current, you will normally destroy the metre. Although more expensive metres will have a fuse to protect the instrument should this occur. Hope this helps Always switch back, should you do this on the mains, you can quite easily set the metre on fire!! CB Eng

oh well here's the thing I don't really care so ... get a life

Basically, all that happens is an integrated circuit produces an output signal of 1010101010101010 over and over again. A second one processes it into a tone such as 1=1.8khz 0=2.6khz. This series of tones is then fed into a piezoelectric sounder.

series circuits have 1 pathway they have constant current(Amperes) not constant voltage.

Resistance=R+R+R+...

My mother is taking it the night before her chemo treatments. to raise her blood platelets

the circuit would not be complete. the lightbulb would not light or the buzzer would not buzz

Hi,

where there is no need of changing the value of resistor then why do you place variable resistor instead a fixed resistor. After all the selection of resistor depends on the cause of use in application. by the way wide range of resistor values are avilable in the market. if the application requires tuning operation then variable resistor is need to be mounted. nothing is mandatory unless the application requires.

The type of RFID tag you are referring to is likely a passive device. It gets read by stimulating it with a certain RF frequency and then looks for a unique return. Hence the tag life is essentially forever.

Universally complete logic module is a programmable logic device capable of producing all possible functions of three variables or less.It can be proved that a multiplexer is capable of producing all possible functions of three variables..So multiplexer is a universally complete logic module.

because they change a materiel's property from it original form (pure form), to a different property from due to doping fig of semiconductor distrot

A mobile phone tariff it cost of any transaction made on your mobile phone.

Decibels (db) is 3 times the log based 2 of the difference in power.

To convert from db to power, divide by 3 and compute the inverse log based 2. For example, +6db is 26/3 or 22 or 4 times the power, and -9db is 2-9/3 or 2-3 or one eighth the power.

If you are attempting to compute voltage, remember that db is power difference, so you need to take the square root of the difference, because power is voltage times current, and current is voltage divided by resistance, so power is voltage squared divided by resistance.

yes transistor is analog device because it can process the analog signal . But it can also used as digital devices as we know transistors are used for manufacturing logic gates and several digital devices as multiplexer and decoder encoder and memories also. it is the basic element of digital devices.

One of the advantages of optical fiber is that it is NOT susceptible to cross-talk.

on applying same power the one which glows brighter is the one connected in parallel connection.

The other materials other than just silicon used to make semiconductors and other solid state electronic devices are germanium and gallium arsenide.
