Firstly, thank you
Secondly, Can you recommend me some websites that deal with this problem (for further understandings) or can you share some documents related to this problem?
Vitamin-C said:Hi,
I have a question for this kind of sinewave generator
using wien bridge:
How precise is this sine wave source ? Is it possible to
create a high SNR (> 80dB) source using this method?
Another question is whether a SNR>80dB sinewave could
be generated by sound card with dynamic range of +/-1V.
Please give me some idea
Vita
As i told, the Wien Bridge oscillator produce (ideally) an *absolutely* pure sine wave, whitout distorsion at all.
