Digital data is discrete data that is used in computers to handle all sorts of digital media, including text, graphics and audio. It only exists in two forms - on and off. This is represented with two digits- 1s and 0s - in the binary format. Since digital data is discrete, files saved in this format can be copied perfectly with no degradation.

In a series circuit there is only one path for current to flow. The current will flow through each good lamp. If any lamp opens (blows), then the circuit is broken and current flow stops. The older strings of Christmas tree lights used to be connected in series and it was hard to fine the blown bulb. If there were two burnt out bulbs almost impossible to find.

The Ampere is the unit of electric current. It depends upon a voltage in order for it to occur, and the Volt is that unit. The Ohm is the unit of resistance and represents the difficulty of moving the electrons by the voltage.

flash type ADC is fastest because in it change takes place simultaneously not sequentially time taken for conversion is 100 ns.

Rf=Distance travelled by pigment/ Distance travelled by the solvent.Rf is the distance travelled by a sample or analyte divided by distance travelled by the solvent front in chromatography

the decision about what to include and exclude.

According to ohm's law V = IR.

So here

I=V/R

=12/4

I=3A

different method are available for converting voice signal to volage ......one method is sence presure variation from the out put of mic by using presure tranducer ..out of transducer should be a volage .this volage is amplified by using amplifier cicuit and it amplified signal or volge is store in to battery or other storig device.......

To avoid that the plates touch each other.

The better the dielectric, the closer the plates can be, thus making the electrostatic field on the opposite plates more intense, which allows for more electrons displaced via the charging circuit to the positive plate and more incomplete atoms (positive charges) left on the negative plate.

Remember: Being the dielectric an isolator, there is NEVER current through the capacitor.

The same way you would with a two-stage transistor. If you know how to calculate the bandwidth for a one or two stage, then you can just as easily solve a three stage circuit. Using the formula for your f(-3dB), for each stage, you simply add another time coefficient tau. One stage has one tau, two stages has two taus, and four million stages has four million taus. Obviously, it's a little more complicated with three stages because you have a input and output resistance on your second stage, and the calculations can get a little sticky if you have a complex third or first stage, but it's all the same. Just crunch the numbers.

A high impedance state is a state where the component hardly draws any current at all.

In most cases it also mean that the component is more or less turned off.

In memory chips, it will keep the memory but no longer accept commands for changing or reading memory content.

In portable measuring devices, it is a state where electronics turn itself off to conserve battery power.

I hope this was helpful.

You should not place a TV on an electric fireplace, unless it is a TV and Media mantle. Most of the standard models are not secured enough to hold the unit. TV and Media Electric Fireplaces and constructed to hold the weight of all of your media.

Chemical Engineering pays the highest salaries coming out of University, but if one decides to do Industrial/Management Engineering and tries to get their MBA, they are seeing a six figure salary with ease.

The future of instrumentation is likely to be characterized by increased integration of advanced technologies such as artificial intelligence, machine learning, and the Internet of Things (IoT), enabling more precise and automated data collection and analysis. Miniaturization and portability will enhance the accessibility of instruments, facilitating real-time monitoring in diverse environments. Additionally, advancements in materials science may lead to the development of more durable, efficient, and environmentally friendly instrumentation. Overall, these trends will contribute to greater efficiency, accuracy, and versatility across various fields, including healthcare, environmental monitoring, and industrial processes.

There are more than one scientists who contributed to the invention of radar. However, the experiments on radar were started by Heinrich Hertz. He discovered that the radio waves were reflected by metallic objects.

An analog signal has a sine wave form and a binary signal has a block "wave" form. The binary signal is either on or off ("up" or "down"), and never anything in between. analog: http://img99.imageshack.us/img99/7723sineuk6.jpg

Open loop means max amplification of an amplifier. if the open loop is very it will probably oscillate since there is not a feedback to control it or it will go to one rail of the other saturated

A digital to analog converter, or DAC, is a device that takes a digital input, usually a word of some size, such as 8 or 16 bits, and converts the value of that word into some analog value, either a voltage or a current.

V = IR

= 8x10-3 (8 mA) * 10x103 (10k)

= 80v
