is when all the persons that are under surveillance know that they are being monitored or recorded...

The chief threat to the envelope industry is alternative means of transmitting information, from mediums such as the Internet, fax machines, voice mail message systems, electronic mail, and other electronic communications systems.

There are several types of material which are used for different -2 circumstances in electronics engineering domain.Widely used semiconductors are-

Silicon - for diode ,solar cell, BJT etc.

germanium- for photo devices,and BJT for low level signal amplification.

GaAs(Gallium Arsenide)- for high frequency devices like tunnel diode Gunn diode.

InP & AlGaAs- for LED and others semiconductor material are also available like CdS,SiO2,GaP etc.

A square wave oscillator is a device which generate the square wave. the circuit of squre wave oscillator can be made by using operational amplifier(uA746) or timer IC 555 and also by other methods.The frequency depends upon the value of R and C inside the circuit.

ANSWER: It is a test equipment designed to provide a rectangle waveform from x volts maximum to x volts minimum.

Because it was a totally New Device. Nothing like ever before!

Roblox cards can be purchased at 7-eleven, Best buy, gamestop, and toys R us. Roblox cards are sold at all seven elevens, but only participating best buy, gamestop, ands toys R us.

remove the phone's battery,u will see all informations like company,model no.,etc

See on a commercial, Or your phone does say it somewere cause mine says it its touch screen and says it on the top ItS a NOKIA tmolible

If you yourself buy the phone, just see the munual instruction. Or you can ask the sellers in phone shop for hep.

The information (card number, card holder name, and other information) is encoded as ones and zeros, then encoded magnetically as data bits onto the magnetic stripe. When the stripe is passed by the read head, it reads how each portion is magnetized (a North or South pole magnetization) and then outputs that as a 1 or 0 to the rest of the system.

It has to do with the fact that what's being plotted isn't a simple function, y = f(x), on an x-y grid, but rather a set of parametric equations plotted on a f(t)-g(t) grid where:

x = f(t) is your input, and

y = g(t) is your output.

Specifically, for the differentiator:

x = f(t)

y = df/dt.

For the integrator:

x = f(t)

y = ∫ f(t) dt.

So, if your input is x = f(t) = sin(t), then your two outputs will be df/dt = cos(t) and ∫ sin(t) dt = -cos(t). That means your coordinate axes for the differentiator and the integrator will be the parametric equations x = sin(t), y = cos(t) and x = sin(t), y = -cos(t), respectively. I don't know if you've ever worked with parametric equations before, but suffice it to say, both of those sets of equations are parametric equations for a circle. I'll add a link to parametric equations below if you want to learn more.

I have two Different Signals, I would like to find the RMS Error Between them, and Mathematically derive how the signals differ from each other.

I would like to find the RMS Error for the two Signals. Please Help.

Thanks in Advance.

A: GND is short for ground. There are many grounds earth ,signal ,power etc. It means a zero potential as a reference to what ever else is connected to

The full history of computers is too long to type in one WikiAnswers answer, so I would recommend Googling it.

Depends, if you have access to acids then computer boards and CPUs have the largest supply of gold but there are small amounts of plating on phones, computers, etc that can just as easily be removed with pliers.

ignoring the iso norms for barcodes, free zone ect.. or making design stuff with the bars like some profile it particulary popular in the cigarette business

PCMCIA generally refers to the expansion cards that you plug into laptop or notebook computers, such as wireless networking cards.

No, it's very expensive.

Clipping level increases.

For example, if the clipping level was 2V before freezing, it will clip at a voltage greater than 2V when frozen.

To charge the X-mini speakers, just plug them into any USB port on your computer or laptop. The rechargeable battery takes 2.5 hours to charge. After it is fully charged, each capsule speaker has a playback time of up to 12 hours. A blue LED light shows when each unit is powered on, and a red light shows when the speaker is being charged.

Download a program such as spacesuit or hyperspaces. also u can look it up on youtube, i heard that there is a demo there 2.

No it does not. Though it did appear to crack down on unauthorized eavesdropping, there are still many ways government agencies can get around this law to get personal information.

Crt monitors,lcd's & led's

This depends on the type of battery. Car batteries are always charged while in use. With other types of batteries, this is not recommended and may result in a battery explosion or damage to the device the battery is powering.

It stands for CeNtRa Science Corp. A Taiwan based company established in 1992, with three factories located in Taiwan and mainland China. They have become the largest MOV manufacturer in both Taiwan and China.

CeNtRa Science Corp. is a leading manufacturer and exporter of power protection equipments, specializing in manufacturing metal oxide varistors.

Auto switching usually refers to the input voltage being automatically selected, therefore one on a laptop probably means you can use multiple charger units with it or it selects its own mains charger voltage.
