An oscillator is a circuit that creates a waveform output from a direct current input. The two main types of oscillator are harmonic and relaxation. The harmonic oscillators have smooth curved waveforms, while relaxation oscillators have waveforms with sharp changes.

dc to ac changing

An oscillator is a circuit which works on the principle of positive feedback and is used to generate signals.

which converts dc to ac is called oscillator.
there are two types of ossilators
based on wave forms namely
1.harmonic oscillator
2.relaxation oscillator

An oscillator is a circuit which works on the principle of positive feedback and is used to generate signals.
oscillator does not have input but it gives output.
In oscillator phase shift is 0 or 360. [AB]=1.

An oscillator is a circuit which does not take any ac input signal and give the output as ac signal

an oscillator is a electronic divec which generates oscillation (waves)desired frequency
