Introduction:
There are so many electronics devices which is widely used in specific purpose in this field.Those many electronics devices need a sources of an energy at a specific frequency which may ranging from few Hz to the several high MHz or GHz. An electronics devices which are used for this purpose is called oscillators . It is widely used in electronics equipments such as radio , TV receivers etc.It is used to generates high frequencies wave (i.e carrier wave ) audio frequency and Radio frequency wave.For the repair radio and television and other electronics equipments, audio frequency and radio frequency is used.Oscillator are extremely used in radar ,computers (electronics) and other devices.
Oscillator are used to produced sinusoidal or non-sinusoidal (i.e square wave, rectangular wave ) waves.It is most useful electronics devices which has widely range of applications in this field .
Sinusoidal Oscillator:
An electronics devices that produces sinusoidal oscillations in desired range of frequencies is known as sinusoidal Oscillators.
Actually , it dose not create energy but only acts as an energy converter, such as d.c energy convert into a.c energy of required frequency .The frequency of oscillations is depends upon the elements used in the its circuits.Alternator is not oscillator although it produces sinusoidal frequency .The main differences between these are one is alternator is mechanical devices having ratings parts whereas oscillator is non-ratings devices.Second is it is used to converts mechanical energy into a.c energy whereas oscillator is used to converts d.c into a.c energy . Third difference is it can not generates high frequencies whereas an oscillator can generates from a few Hz to several MHz.
Advantages:
Electronics oscillator have the followings advantages:

Advantages:
Electronics oscillator have the followings advantages:
- It has very high efficiency.
- It can produces waves from few Hz to very high frequencies MHz.
- It is non-ratings electronics devices .As a results it has little tear and wear .Hence it has more longer life.
- The operation of an oscillator is very silent because of absence of moving parts on it .
- It has good frequencies stability.
- The frequency of oscillations can be changed when needed.
