PHASE LOCK LOOP
DPLL Image
o The PLL uses phase lock to perform its intended function.
o Before phase lock can occurs it must have frequency lock.
o After frequency lock has occurred, the phase comparator produces an output voltage that is proportional to the difference in the phase between the VCO output frequency and the external input frequency.
o When there is no external input signal or when the feedback loop is open, the VCO operates at a preset frequency called its natural or free-running frequency (fn) .
o The natural frequency is the VCO’s output frequency when the PLL is not lock.
Short for phase-locked loop, an electronic circuit that controls an oscillator so that it maintains a constant phase angle (i.e., lock) on the frequency of an input, or reference, signal. A PLL ensures that a communication signal is locked on a specific frequency and can also be used to generate, modulate and demodulate a signal and divide a frequency.
PLL is used often in wireless communications where the oscillator is usually at the receiver and the input signal is extracted from the signal received from the remote transmitter.
Digital PLL (DPLL)
Digital PLLs are a type of PLL used to sychronize digital signals. While DPLLs input and outputs are typically all digital, they do have internal functions which are dependent on analog signals. There are four basic components of a DPLL.
Having a webportal is the best way to serve prople if you are associated with a corporate ot Institution or may be freelancer serving society in any way. Webportals are not just staic websites ,they are dynamic in nature and provides the best way to satify the requirements of each single user of the system(Ideally).This may be a total interactive platform between a user and others associated with this.
What are the advantages if I have a webportal for my institutions/Corporate sector?
If you have a webportal then no matter how far the memebers and peoples who are attached with
your Institutions/Company , they will be always in touch through the services provided by the webportals.
From educational point of view in can be said that the webportal can be an easy way and service to help all students by helping them involved in a total way from knowledge sharing to direct teacher interaction and also from learning to implementation by deep sharing of informations and knowledge between teachers ,friends, seniors,juniors and others.
IS there any other advantage
=======================
There may be other indirect advantage.
For eaxmple when you have an active webportal online ,that means your site activity and portal is viewable by all the world.So people residing outside the country may come accross your portal activity and may
be influenced enough to join the institution as a foreigner candidate(Provided you have the foreign student intake capability according to your country rules).
So in brief
having a webportal means lots of students teachers attached with it.(Please note I am talking about educational webportals) So have fully functional student-teacher community active round the clock(Ideally).One such kind of organization that can give these services at FREE is

British researchers reported that they had found “convincing evidence” to confirm who will be affected cannabis DNA (DNA), and may lead to cancer.
University of Leicester in Britain, said press release on the 16th, the school researchers and colleagues in Sweden launched a joint in this study. They developed a new “high-sensitivity liquid chromatography tandem mass spectrometry”, clearly shows that marijuana use on the impact of DNA. They focus on marijuana and tobacco, there are elements of the general toxicity of acetaldehyde have been studied, results show that it can damage DNA and lead to lung cancer and other cancers.
Singh said the researchers, the hazards of smoking have more research, but the dangers of cannabis is a relatively small study. Due to the relatively poor flammability marijuana, cannabis brought naphthalene, benzo anthracene, benzopyrene, a carcinogen such as smoking more than 50%.
He said that some people often mixed with cannabis in the smoking of cigarettes a day, smoking 3-4 cigarettes that of bronchial damage equivalent to smoking 20 cigarettes or more general.

We failed to save the student from being ragged to ultimate death of 1st year student of Hamachal Pradesh.
Stdunet of Dehradun’s school can’t save his ears from raggers and there are many more results all around the INDIA.
Though the Govt. has taken very strict steps in this matter but still the incidences are still occuring either in big scale or in small scale.
Whenever a student takes admission to new college the challenge is to adopt the new structure (educational) and environment of the college.Another big challenge is wining over the fear called Ragging.
The untold truth is that if you pass the ragging test conducted by your seniors then you will stay peacefully during test of your studey else …..may have a big problem.
Most of the parents stay in anxiety about how to cope with this problem,how to mentally prepare their sons/daughters about ragging,where to go for justice if students get ragged.Most of the parents are in dark in these matters.
Whenever a person’s own son/daughter become a victim of ragging then everything becomes so much dishevelled that people can’t think where to go ,whoose suggession is to take or compromise with the issue for the future of the student (as sometimes college also wants to conceal the matter).Students also lost their self confidance as wel a s get disappointed.
So Blog readers do you have any suggessions in this matter ,then write your comment.
Part II Coming Soon……
In The next part I will discuss about the self confidenace building for facing the ragging..
If Anybbody has any good ideas of how to protect ragging and how to cope with ragging activities,their comments are welcome to this post.

It has been learned, including Tokyo, Kanagawa, Yamanashi, Nagano and so on are a total of about 6 counties of more than 2,000 stations, 861 stations have started to join the ranks of sales of bio-fuel, accounting for about gas stations in the region 40% of the total.
At present, sales of bio-fuel standards for gasoline in accordance with the proportion of more than 1% in a mixture of sugar cane and other plants as raw materials to produce bio-ethanol, as a result of the Japanese Economy, Trade and Industry and oil Union of biological fuel and regular gasoline for the difference between the part of bio-fuel market and regular gasoline prices the same as regular gasoline can be directly added to the tank car.
