What are the uses of logic gates?

Logic gates are in fact the building block of digital electronics; they are formed by the combination of transistors (either BJT or MOSFET) to realize some digital operations (like logical OR, AND, INVERT ). Every digital product, like computers, mobile, calculators even digital watches, contain logic gates. The use of logic gates in digital world can be understood better by the following example: the single bit full adder in digital electronics is a logic circuit which perform the logical addition of two single bit binary numbers (a,b,cin) a and b are the the two binary number of single digit (either 1 or 0) and cin is the carry input . say for example a,b,cin= 1,1,1 gave an logical sum output of 1 and a carry of 1 , a,b,cin= 110 gave sum= 0 and carry of 1. Now this adder can be formed by the combination of many gate like by using NAND gates only. or by using XOR , AND ,OR gates and so on. So, in a nutshell, the adder which is of great importance in your computer processor and also in many more applications is basically built from the logic gates.

Electrical Wiring

Should you wire a pool pump to 110 or 220 volts?

The most important thing for safety is to wire the pump to the correct voltage marked on the pump.

All else being equal (i.e. the cost of the pump), use 220 -- the higher the voltage the less electricity lost to resistance and heat.

ANS 2 Most modern pool or spa pumps are convertible (at the motor connection) Connecting to 220 is definitely more efficient.

Ans 3: 110 v is safer, with a lower risk of shock. For a pump of 1 HP or less the power lost in the wiring is very small if the right wire is used.

How do you buy Mobile Phones from Egypt?

Well, it's pretty simple. Unlike the U.S, you don't have to buy a plan or anything. Just take your money, go to the shop, pay and get your Mobile :). Then buy a simcard, which is equivalent to about $3. Whenever you need to use the phone, buy a recharge card for the amount of money you want (very cheap) and recharge your pone credit :D

You have two Sleep Number beds with two separate remotes but both remotes control both beds how can you separate them so that they only control one bed?

. I'm Stephanie and I work for Select Comfort's online Customer Service team. I am very sorry for the issue you are having and would love to help you. If your beds are over 2 years old, you will want to do the following steps: Unplug both of the base units.

Plug in one of the base units. [You must complete the following initialization process within 60 seconds of plugging unit in.]

a). Use the remote that goes with the base that is plugged in.

b). simultaneously press both the firmer and softer buttons on the right side of remote. The display will count down from 10 to 1, then " -- " will appear, then "C1" will appear.

c). Release both buttons when the "C1" appears.

d). While C1 is displayed, again simultaneously press both the softer and firmer buttons. "1C" will appear.

e). Release the buttons and the proper sleep number will be displayed.

f). Allow the remote to go blank.

Unplug the base unit that you just initialized and go through the same process with the second base and remote. Allow the second remote to go blank.

Plug the first base in. Now each base will only respond to its specific remote.

Note: If you attempt this sequence a second time immediately following the first without unplugging the unit, you may cause an E0. If you see an E0, simply allow the remote to go blank, then you should be able to use the remote with no issues. If you still experience issues, unplug the unit, wait 20 seconds, then follow the sequence for initialization once again.

If your beds are newer than 2 years, please contact Customer Service at 1-888-411-2270 and we will help you troubleshoot.Thank you for choosing the Sleep Number bed.

What are the qualities a electronics professional need to excel in his field?

A: This was asked before and the criteria remains the same a very hi reasoning quality to think concepts and troubleshooting along to know which book to look up for an answer. Nobody knows it all nobody can. To complex, to many fields

Just an addition to the above answer, I agree that choices are broad, but, then its a good thing also. By Identifying your interest area, you can be a master of that one specific field.

The initial step is to know the various specialization in the field of Electronics, having a superficial knowledge of them and then decide, what intrigues you most?.

I hope that part is already covered. Next step might be in the identification of the current direction of the research going on. For this, reading magazine articles are more useful over journals.

I hope this was helpful.

Computer History

What else is a computer tower called?

A computer tower, also known as a computer case, is the enclosure that holds many components of a personal or office desktop computer. A computer tower can come in a wide variety of shapes and sizes and can also be made from a wide range of materials including steel, plastic, aluminum and more. The sizes of a computer tower range from small mini-towers to medium sized mid-towers and all the way up to full-size towers, depending on what the computer is being used for and how powerful it is.

There are several computer components that can be commonly found in the computer tower of a home or office computer. Typical components include the motherboard, hard drive, power supply, optical drives and floppy drives as well as other parts. The locations of these components within the computer tower is usually dependent upon the size or shape of the tower itself, but they are also found typically in the same places on the tower for the sake of convenience. For example, the CD, DVD or floppy drives can usually be found in the front of the computer tower for easy access, while the power supply is usually located in the back to keep the cords out of the way.

Why negative feedback used in amplifiers?

transitors amplify signals in a very non-linear fashion. somehow (i don't know how), adding in the negative output of the transistor (negative feedback loop) makes the output much more linearmostly for stabilization, but there can be other reasons in specific cases.

What is the difference between HDMI 2x 3x 4x 5x etc?

2x, 3x, 4x etc. is the number of HDMI ports.

I got the followin from HDMI.ORG

HDMI is the global standard for connecting high-definition Consumer Electronics and PC products. It's the uncompressed, all-digital interface that delivers both dazzling quality and unmatched ease of use.

HDMI technology provides the highest possible signal to meet the needs of today's - and tomorrow's - HD entertainment systems. With a single cable, it transmits:

  • digital video
  • multi-channel surround sound
  • advanced control data

More than 800 manufacturers have adopted the HDMI standard, including some of the world's most trusted brands.

  • 229 million HDMI-enabled devices shipped in 2008. 300 million are more projected in 2009.
  • Market research from In-Stat projects over a billion HDMI devices in the market by 2010, when every new digital TV will feature at least one HDMI port

HDMI connectivity is already standard on a wide range of products:

  • HDTVs
  • Blu-ray Disc players
  • multimedia PCs
  • gaming systems
  • digital camcorders, and more.

With HDMI connectivity, you get it all. The convenience of a one-cable solution, plus the power and performance of a high-speed digital link. Now and in the future, it's the best way to connect HD.
