Greetings everyone, i have a assigment and i need to creat a wien bridge oscilator that uses potentiometers so the out frecv can be modified between (10, 14 )Khz...and the out voltage between (6,9) V ... i allready made a sketch but i just cant figure out how to do this...every time i try to make the amplitude bigger the frecvency changes and the other way around. Please, can someone help me ?
Thanks Godfreyl for your reply. I didnt add any potentiometers since i didnt really know wher e to put them ...could you please make a quick sketch on how to place them?...dosent have to be exactly just a quick paint sketch so i get a basic ideea cause im preety lost here
A 741 opamp is 45 years old and works poorly above only 9kHz. Usually a modern audio opamp is used that works well to 100khz.
The diodes in the circuit limit the amplitude by causing clipping distortion. Usually a linear Jfet is used.
