Basic learning conspet for Mobile Jammer

Project on mobile jammer:

Before starting this project we must know some basic information.

1)what is Mobile jammer?

2)How it works?

3)Jamming techniques

4)Design parameters(or)specifications

5)Regulated power supply

6)How we generate large amount of frequency.

7)Basic information about oscillator

8)what are required things for developing mobile jammer

9)And also know where these jammers are most useful in our daily life

Brief introduction about regulated power suply

Regulated power supply(RPS) is use full for converting Ac power to Dc power.
Block diagram for  RPS:

It has 4 main steps to construct RPS:
 1)A Step down Transformer
 2)A Rectifier
 3)A Dc Filter
 4)A Regulation

1)A Step down Transformer:
                                       It will requires Ac power from the load.
2)A Rectifier:
                    It has mainly contain 4 diodes opposite to each other.It will convert full cycle to half cycle as like as in block diagram
3)A Dc Filter:
                    From rectifier will give high ripple content.But we need only pure ripple dc wave form that why we are going for filtering.It contains mainly capacitor and resistor
4)A Regulator:
                    Regulator is useful for constant dc power supply

so friend try to develop Regulated Power Supply in your lab..all the best friends..

Pre plane for TCS to get briliyant students for their company

HAI friends TCS(TATA CONSULTANCY SERVICES) will conducting a special online exams.If we participate those exam there are many uses further our future life if we select one of the top ranker in that exam we will directly enter into interview round not at all written test and hr round.And top three ranker will get a prize money and also a job in that company.Codevita and techmony are mainly conducting TCS.Engineering 1st year and 2nd year students are eligible for this exam.So friends be cool,write well,get experience and also win some valuable prizes and if you interested  TCS will give job after completion of your engineering.

How to start gate preparation

Nowadays all students are very much interested for their higher studies...
    Gate is best one for engineers.In our B.tech life starting 2 years are very very important why because lot of syllabus covered this 2 years.3/4 of our B.tech syllabus will covered starting 2 year that why we must focus those subjects and the fact is max syllabus from gate question paper having this 2 years syllabus.we are thinking gate questions are easy.It is only true when we have that much of knowledge and they are giving our basic subjects with different way.Why because they are testing how the student mind set,how he(or)she solve the problems and how he(or)she know basics regarding their branch.In gate aptitude also plays a main role so better to prepare those topics

Flexible energy storage is smaller, cheaper, better

Flexible energy stirage is smaller,cheaper,better and more use full...........

summary:

Engineers have developed a way to make a magnetic material that could lead to lighter and smaller,cheaper and better performing high frequency transformers,needed for more flexible energy storage systems and
widespread adoption of renewable energy.

 

Know about Electronics & Communication Engineering

Electronic and communication engineering is also referred to as  electronic engineering is an engineering discipline which uses the scientific knowledge of behavior  and effects of electrons to develop components,devices,systems or equipments(as electron tubes,transistors) that uses electricity as part of its  driving force.Both terms denote a broad engineering field that encompasses many subfields including those that deal with power,instrumentations,semiconductor circuit design and many others.

The term also coves a large part of electrical engineering degree courses as studied at most European universities In the U.S.,however,electrical engineering encompasses all electrical disciplines including electronics.

History of electronic engineering:

Electronic engineering as a profession sprang from technological improvements in the telegraph industry in the late 1800s.people were attracted to radio and telephone industries in 1900s.People were attracted to transmitting.Many whio went into broadcasting in the 1920s were only 'amateurs' in the period before world war1.

The modern discipline of electronic engineering was to a large extent born out of telephone,radio,and television equipment development and large amount of electronic systems developments during world war2 of radar,sonar,communication systems,and advanced weapon systems.In the inter war years,the subject was known as radio engineering and it was only in the alte 1950s thet the term electronic engineering started to emerge.

The electronic laboratories{bell lab in U.S.A}created and subsidized by large corporation in the industries of radio,television and telephone equipment began churning out a series of electronic advances.In 1948,came the transistor and in 1960's the IC to revolutionize the electronic industry.in the UK,the subject of electronic engineering as university degree subject around 1960.Before this time,students of electronics and related subjects like radio and telecommunication had to enroll in the electrical engineering department of the  university as no university had departments of electronics.

Know What is SUCCESS

SUCCESS:Achievement of an action within a specified period of time or within a specified parameter.Success can also mean completing an objective or reaching a goal.Success can be expanded to encompass an entire project or be restricted to a single component  of project or a task.It can be within the workplace,or  in an individual's persons life.For example, an individual's personal goals is to be accepted in a new career,success would occur after the individual has been officially accepted into his or her new place id employment
