What are the uses of oscillators in electronics?

Answer 1

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.

Answer 2

Oscillator- 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.

Answer 3

Basically 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.

Answer 4

oscillators are used for tuning the desired frequency from several range of frequency. and they are used for provide the carrier frequency to modulator circuits. and they can also used for several frequency generation in electronics circuits.

Answer 5

the job of oscillator is to produce a sin wave with desired frequency
