The main differences between amplifier and oscillators
| Amplifier | oscillators |
|---|---|
| Amplifier is an electronic circuit which gives output as amplified form of input. | Oscillator is an electronic circuit which gives output without application of input. |
| The amplifier does not generate any periodic signal. | The oscillator is generating of the periodic electronic signal. |
| Amplifier uses negative feedback. | Oscillator uses positive feedback. |
| Amplifier operates as a multiplier. | Oscillator operates as a source |
| The Amplifier provides amplified signal. | Oscillator is gives oscillatory signal. |
| Amplifiers do nothing till input signal is fed to the input. | Oscillators produce signals from the moment of powered. |
