I'm working on designing a kHz sine wave oscillator whose output amplitude is quite insensitive to temperature. Frequency drift is really not a concern; the nominal target will be near 30kHz but even 1kHz drift over temperature would be OK. Harmonic distortion is not a huge concern, having the 3rd harmonic at -40dB down would be acceptable.
I have a question that im not sure about. I have a fundamental of 70vrms 50Hz, a 3rd harmonic of 23vrms and 5th harmonic of 14vrms. the frequencies of the harmonics are 150Hz and 250Hz respectively.
