Anyone has ideas? Thanks

Hope this helps. If u find any other way let me know!! Thanks,

Anyone has ideas? Thanks Click to expand... If your input frequency is a triangle or square wave, it owns harmonics. With a bandpass, select the required frequency (it will be a sinus), and amplify (& limit) it, if necessary.
