There are many different types of multiplexers. However, the basic function of all of them is to combine multiple signals into a single 'channel' for transmission. At the other end of the channel, a demultiplexor is responsible for splitting the combined signals back into the original, separate signals. Different types of muliplexors include Time Domain (TDM), Frequency Doman (FDM), Statistical (SM), and Space Domain (SDM). In a TDM, for example, every signal is given a specific duration time slice. This means that the bandwidth of the channel between the mulitplexor and demultiplexor (mux and demux for short) must be greater than the sum of the bandwidth of all of the input signals. So, 10 1MHz signals might be multiplexed into on 11MHz signal for transmission across a microwave or fiber link. Much signal transmission equipment is available with the mux functionality built in, freeing the designer from having to worry about it as a separate condition. For example, a fiber transmitter may have several high speed data ports. It senses the bandwidth of each signal, then automatically adjusts its own output bandwidth accordingly. Finally, muxes can be connected to other muxes in a hierarchical configuration. The phone company used such a configuration for long distance traffic, using local loops into groups, into super-groups and so on until satellite bandwidth was reached.

A sound system works by converting sound waves into electrical energy. The electrical energy is then converted back into solid energy that results in sound.

A "C" battery has a 1.5 Volts same with AAA, AA, and D batteries.

Hi, Here is something i found over net. In a weighted hammer action, all keys are equally weighted. In a graded hammer action, the keys become lighter as you move towards the treble region. -shan

yes. Just hook it up to the computer hardware. But you cant't get cabel or watch a tape on it. there are converters that convert NTSC signal into computer signal. However they run around $100-$150. update June 27, '07: my Grandtec GVC-1000 cost only $60 and works very nicely. It even has a remote control. It has inputs from Composite Video (RCA plug), S-Video, and VGA, and output to VGA. So you can use it to switch between VCR, DVD player, and computer, all through the same monitor. The VCR or DVD player provide the TV channels if you want them. And my computer monitor has much better resolution than my old t.v. did. you can buy a 'Scart to VGA SyncBlaster Cable' from Maplin Electronics

It's apples and oranges. one is nothing like the other. The PS3 is a game console that goes in a room connected to a HDTV and has an internet connection so that it can browse the web download movies and play games. An iPad is a portable device that you carry around to use Most people would like to have both and not one or the other.

I Run a 800w Kenwood 2 Channel.. it is only 2ohm Stable. I ran the subs in parallel so I belive they are 2ohm as well. The kenwood i have i should be able to run at max but the subs i don't think are the best quality because they sound great at about 1/2 volume but when i give them what the amp has to offer it seems to be a bit much wich is why i think the subs are overrated power wise. But the amp at in between 1/4 and 1/2 gain turned up seems to be a good match.

We can hear almost all amplitudes(except very small amplitudes). Amplitude determines the intensity(i.e., loudness) of sound wave. Intensity is proportional to Amplitude squared. So there is no upper limit for amplitude. But very loud sound(high amplitude wave) can be harmful for ears.

Actually there is a frequency range(20Hz to 20kHz) that we can hear.

You need to have an action replay. Download the codes from Code Junkies then put the Action Replay in the DS/Ps2/Gamecube/Gameboy Advance/etc.

In a few seconds it should load and you should have all of the codes you downloaded. (If you don't you can manually input them) Then browse through the list of games until you get to the game you want to use the cheats on. Then just activate the cheats (If the is an 'M' cheat it MUST be activated!!!) and swap, insert, the game that you activated the cheats for.

Hope I helped

Well you have to buy a desktop police scanner at radio shack or online, then put the walkie talkie on vox mode next to the speaker of the scanner. If you want to listen to police scanners for free, download free online scanner from this link witch you can copy paste, http://www.wlfd.com/staticpages/index.php/scanner_guide F.Y.I. This program is free therefore you can't control the scanner, but you can find one close to your area. Hope this helps!

Although most chargers are equipt with auto cut off when the battery is charged, the battery will only draw enough power it will take. It power is forced, it could result in an explosion. You can damage or blow up the battery.

simply , it is used to control the circuit , for example if i have a lamp ( or LED) and i want to control when it should be on i used sequential logic gate ( or flip-flop ) with an exact input ( say '11' ) .

ANSWER: There are no sequential logic gates. But there decoders and multiplexers whereby an output can occurs only when reaching a code or an address

The human eye has its greatest sensitivity around 555 nm (540 THz), in the green region of the visual spectrum. This makes green lasers appear to be brighter than other lasers of the same power but different color.

go to this site you can get from 1mw all the way up to 1000mw's on this site have fun and you be on this site for a long time they build good inexpensive laser's. here is the site and sure fire are good battery's they use them.

LG Fully-Automatic Front Loading Washing Machine

I think that this is a standard buy by which one can wash all the clothes of their household. With features like that stainless steel drum and the auto-restart, if there’s ever a power cut, it becomes an essential buy for anyone wanting a front load washing machine.

no, if you charge 9 volt battery with 12 volt battery you will destroy 9 volt battery

I am the one who question~

The more data:

I mean,there is AAA type dry cell with 1.5V and AA type dry cell with 1.5V as well and square cell with 9V.So what's the realtionship between all these?Is there a realtionship I mean?I suppose there's...Thank you for answering my question:)

Answer: For non rechargeable batteries, there is 1.5 volt per cell. So AA, AAA, D, C, etc. batteries have one 1.5 volt cell. The size of the cell is different in each, which allows larger current flow from that particular battery.

None volt batteries are typically 6 of these cells stacked in series within a single battery. For cheap 9 volt batteries, there may be only 5, as the actual voltage is usually higher than 1.5 volts per cell (each cell voltage is intentionally made larger).

wikipedia has a pretty good explanation - search for "nine-volt battery".

Another way to glean more understanding is to simply take a few apart - make sure you wear some protective gloves and eyewear (some of these chemicals can be very corrosive).

Hope this helps.

The fan itself might use 40 Watts, add to that the power used by the lamps (maybe 3*50 Watts) and the sum is just under 200 W when all the lamps are lit. So under one Ampere in the example given.

The parts of a light bulb are the glass envelope, mixture of inert gases at a lower pressure, and a screw cap. Inside of the light bulb is the coiled tungsten filament, support wires, glass fuse enclosure, connecting wires, and the electrical contact.

An iPod is made out of glass,plastic,metal,wires,and a sensor for tough screen.

The general answer is that the electric motor makes it go. Electricity is converted to mechanical energy by the motor, and the power is transferred through gears (to correct speed) and coupled to the mixing head or to the mixer blade shafts.

Pros-

-if you have a good camera that you can control the lighting and exposure situation, you'll take incredible pictures.

-photoshop allows you to easily fix small mistakes you might make

-image stabilization on the camera & automatic focus

Cons-

-films cameras can give a much more natural look

-improper use of digital editing will ultimately make the pictures look fake

-almost complete control of the end result image.

-Automatic mode on digital cameras are extremely weak in low lighting situations

It is a very good question you ask because Craigslist gets a truly remarkable amount of traffic. As a web analyst I would first like to point out that 'hits' is a concept that is rarely used these days. The short version of the reason why is that 'Hits' can refer to everything from visits from search engine spiders, crawlers, poppers, screamers, and a host of other non-human web denizens. Craigslist gets visits from around 40.8 Million people per month. 40% 18 – 34 38% 35 - 49 years old 54% Male 78% Caucasian 7% Afr. Am. 8% Hispanic 5% Asian 17% $0 – 30k 25% $30 – 60k 27% $60 – 100k 32% $100k+ 43% College Graduates More information is available on web analytics at www.atlantaclickadvisor.com

There is no specific answer. It's like asking how long it takes to fill the gas tank in a car. There is chemical energy in gasoline, and also in the battery electrolyte. How much energy was taken out? The more that was taken out, the longer it will take to put it back in. And what is the original capacity of the battery? There is a limit on how fast the tank can be filled or the battery charged, too. This will also affect recharge time. To some degree, the capacity of the charger to deliver "optimal" charging amperage contributes to the recharge time. Lots of variables, lots of uncertainty.
