Hi All,

May I know what is harmonic oscillator? how does it work?

Thanks.
 

Re: harmonic oscillator

A harmonic oscillator is a one which generates frequencies which are integral multiples of fundamental frequency
 

harmonic oscillator

it is used when there is no direct way to have such high frequency. thus a fraction of it is used. an oscillator is designed in low frequncies and then the output signal passed through a nonlinear device such a diode. output signal has harmonics of the main frequency. needed harmonic is filtered out and then amplfied. this process maybe repeated to reach to the desired frequency
 

Re: harmonic oscillator

just check this out, everything's got explained pretty clear!

its a sinusoidal oscillator that has an ac outputbut no ac input

May i know LC oscillator can consider as harmonic oscillator or not? or how to implement it using electronic component?
