to produce sustained oscillations without any ac input.it is nothing but an amplifier with positive feedback and without input.it just converts the noise in the circuit and amplifies it to produce oscillations.

∙ 13y agoOscillator- Another important circuit like an amplifier in electronics. It is the circuit which generates alternating voltage. For this, it requires direct current ( d.c. ) power supply.
Purpose of an oscillator-
Sinusoidal or non sinusoidal waveform of low or high frequency can be generated by an oscillator.
Applications of an oscillator-
Oscillator is widely used in radio transmitter and receiver, TV transmitter and receiver, audio generator, RF generator, waveform generator, function generator, telemetering, in radio telephony as carrier, in radio telegraphy, in induction heating, in dielectric heating, in remote control, in digital clock, To produce ultrasonic waves, To produce accurate time base and many other electronic equipments.

∙ 12y agoBasically an oscillator is a circuit that is used for producing oscillations of current.
They are mostly used in radio, to provide a carrier wave for a transmitter, or a local mixing frequency in a superhetrodyne receiver.
They are also used at sound frequencies, for Musical Instruments such as a synthesizer, like a Moog or Korg.

What products use the capacitor?
The products that uses the capacitor are filters and oscillators.
Classification of oscillators?
Phase-shift oscillator Armstrong oscillator Cross-coupled LC oscillator RC oscillator
What are the differences between sinusoidal oscillators and non sinusoidal oscillators?
sinusoidal vs non sinusoidal
Why only low frequencies are used in hartley oscillators?
an Hartley oscillator uses a tapped inductor ( i.e an inductor with an additional connection at a suitable position in turns of the coil. ) with a specific tap ratio as per the circuit gain and design. For Low Frequency oscillators large inductances are required which have large number of coil turns. It is possible to get suitable ratios for such values hence this circuit is prefered.
Why LC oscillators are not used for low frequency?
They are not suitable for use as extremely low-frequency oscillators because the inductors and capacitors would be large in size, heavy, and costly to manufacture.
What products use the capacitor?
The products that uses the capacitor are filters and oscillators.

Reason for using wire wound resistor in electronic circuit?
There is many uses for the resistor in electronic circuits, like current limiting, voltage division, R/C oscillators and many more. Without the resistor electronics is not possible
State four types of LC oscillators?
Four types of LC oscillators include voltage controlled oscillators, drift control oscillators, crystal oscillators, and tuned circuit oscillators. A tuned circuit oscillator is the most common type of oscillator.
What are the Uses of chemistry in electronics?
Electronics use ultrapure crystals and reagents.
What does a synthesiser do in music?
With the help of synthesiser, the sound of the existing instruments could be emulated. It also uses electronic oscillators to create an artificial sound.
Closed loop gain for feedback oscillators?
Feedback oscillators have a closed loop gain of
