How do you increase an MP3 sound quality and volume without downloading anything if not what's the easiest and cheepest way to increase its quality and volume?

To increase clarity you need to change the bit rate of the song played and to increase volume you can amplify the signal using software such as Format Factory etc..

If you amplify the signal then the clarity will reduce.

Why is the capture range less than the phase locked range?

Once the PLL is in lock, what is the input (or VCO) frequency range for which it can keep itself locked is the lock range. When the PLL is initially not in lock, what frequency range can make the PLL lock is the capture range. Lock range is the parameter you should be interested in if you are looking for it's tracking behavior. But in CP PLLs, both the lock and capture ranges are the same.., limited only by the VCO's tuning range.

In modern PLLs capture range and lock range are the same. But by definition these are different and this relaxed usage in journals and books leads to these confusions.
Capture range and pull-in range are the same. Both refer to the ability of the system to acquire lock (from an unlocked state) to a frequency. Here the VCO is running at some arbitrary frequency and the disturbance required at the input to make it respond to the input disturbances thereafter is quantified as capture range.
While the VCO is responding to the input disturbance (in-lock), the amount of disturbance at the input that will cause the VCO to shun the input and run freely is quantified as lock range.
Always lock range is equal to or greater than the capture range.

Definitions from the web
Lock range is defined as the band of frequencies centered on the VCO's natural frequency over which a PLL can maintain frequency lock with an external input signal.

Capture range is defined as the band of frequencies centered around the VCO natural frequency where the PLL can initially establish or acquire frequency lock with an external input signal from an unlocked condition.

What output devices did Donald Bitzer design?

Bitzer co-invented the Plasma Display, along with H. Gene Slottow and Robert Willson back in 1964 at the University of Illinois at Urbana-Champaign for the PLATO Computer System. The original plasma display was a bright orange monochrome screen.

Why does my iMessage say This person is not regestered with iMessage. when the person is?

How do you upgrade your Samsung SCH-RL20 to a 4.0?

More information on this device is needed, as a search by that device model number doesn't produce anything on search.

What is full scale deflection?

Full Scale Deflection is equal to the max value on a scale or meter. If a thermometer reads from -20 degrees to +100 degrees, the full scale deflection = 100 degrees and the range = 120 degrees

Who created electronic first?

No single person created electronics. It took the work of hundreds of scientists over about two centuries to discover and quantify the natural phenomena on which it is based, then roughly half a century for engineers to create the technology with those phenomena. Some of these people were:

  • Volta
  • Ampere
  • Watt
  • Ohm
  • Henry
  • Tesla
  • Edison
  • Fleming
  • Marconi
  • Armstrong
  • Heaviside
  • Hertz
  • etc.

Will a 240v sewing machine work at 230v?

Yes, electronic products need to work over a range of voltages as the mains is not maintained at exactly 240V or 230V. Typically they have a range of at least 10% and normally much more. So it should work down to at least 216V.

What is difference between electric and electronic?

Sometimes the terms are used interchangeably. But roughly speaking, electric circuits include voltage sources such as batteries, as well as "passive" components, such as resistors, inductors, and capacitors - whereas electronic circuits include those, but also additional components with a non-linear characteristic (i.e., a more complicated behavior), such as rectifying diodes and transistors.

What is the best way of breaking a phone inconspicuously my phone is really annoying i hate it but i can use another one until its broke any ideas on how i can break it without my mum finding out?

breaking your phone isnt a good idea...but if u REALLY hate it then i would advise to just throw it away. but honestly. its not a good idea to break it in the first place.

How to protect a pdf file?

A PDF file can be protected in many ways. Some methods are most secure while others can be superficial.

The first choice for most people will be the use of Adobe's own solution known as Acrobat. With Adobe Acrobat a PDF can be protected using password and/or expiration. There are many other PDF creators that also offer password and expiry date protection and the user needs to beware of imitations because many PDF converters do not properly protect the PDF. To enforce any limitations on a document it needs to be encrypted to prevent normal viewers from ignoring the protection. So when it comes to general distribution most authors will want to use Adobe tools because they are more widely used.

But if your document requires bullet-proof protection you need to look at a more secure solution, one that your users cannot use other software to remove the protection. PDF protection and DRM are popular targets by nuisance developers and one only has to perform a web serach on "remove protection from PDF" to realise just how many apps are available for removing PDF protection and just how exploitable these so called "protect" solutions really are.

To further protect PDF an author may also want to prevent unauthorised sharing. Here DRM can be used to ensure that only the author assigned users can open a document. But as with password protection DRM can also be exploited, that is, unless you use a document solution that is designed for protection from end to end. Copysafe PDF is such a solution and by using its proprietary reader with DRM options you can distribute PDF documents by email, download and on disk with the most secure and unexploitable protection from all copy including screen capture.

What are the Advantages of Medical Transcription combined with Electronic Medical Record?

When the Electronic Medical Records (EMR) were being adopted by the industry about 4-5 years back, most of the experts and analysts thought that they would eliminate Medical Transcriptions and would make physicians more of a computer-operated robot who just focuses on his monitor rather than the patient. However, over the years, physicians have realized that the need to document the encounter on medical transcriptions is of paramount importance. Quite a few physicians rely on documenting encounters on medical transcriptions with their staff members documenting the same in the EMR later on. Data can be entered in an EMR via two methods: direct entry by the physicians through point and click templates or using SOAP notes. This really makes creating a medical transcription a breeze as compared to duplication of work in the paper-based process and the hassle of writing everything by hand. Most present-day EHRs can also receive dictation by voice to create medical transcriptions.

How do you block texting on ATT?

You go to you closest AT&T store around you and you go up to one of the front desks and tell the person what you want to do; Block Texting for an example, then they will ask for you cell phone number that you would like to block texting from. They will ask for you identification (I.D.) then they will process it through their computers and then it will be done.

How do you connect mettler Toledo wildcat scale RS-232 data output to a computer interface to document transactions and create records electronically?

Did you get this question answered yet? I have a site in Manila with a query about connecting to a Wildcat balance. I think the data string which is transmitted by the balance in continuous mode is quite tricky to interpret, as it contains BITS within a STATUS WORD A, B and C for various configuration and value breakdown. google Toledo Mettler Wildcat to find a user manual at a company called northshore . Appendix explains how the comms works. But it is confusing.

What is pre-emphasis and de-emphasis in FM?

In FM, the effect of noise is more on higher frequencies when compared with low frequencies. Therefore in order to have high signal-to-noise ratio(low noise), the high frequencies are amplified at the transmitter side and for compensation deemphasis(decreasing the amplitude of those boosted frequencies ) is done at receiver.

How do you fix a broken iPad keyboard case charging cord outlet thing?

you can try to hold the cord in for the entire charging time, assuming you have time AND won't mind temporary strange looking nails.
