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.
I tried to construct a harmonic oscillator circuit that is to be loaded with ohmic resistance and integrated in a larger circuit. No oscillation occurred.
So I created a simple version and try to simulate it in Multisim (schematic attached). This version does not oscillate either (in simulation). Switch operations: S1 is closed, S1 is opened, S2 is closed.
Hi A while back i got a new monitor and for a while everything was fine BUUUT then i started to get a ghostly distortion issue. http://postimage.org/image/rli1pub49/
If you look closely you can see a sort of ghost for everything on the desktop
Has anyone ever experienced call distortion on their G2? I'm on sprint. And while i do like the phone, the distortion or screeching on calls is disturbing. This is my second one on day 6 out of a 14 day period.
