sinewave generator

From the output generator, the sine output waveform is let say -15 to 15, how can i do so that the waveform move to above 0, which is 0 to 15. I just need to move the waveform above 0. Who can tell me how to do it?






Thanks...
 

Re: sinewave generator

You have to divide the input signal by 2 and add dc offset of 7.5V .. see attached picture ..
If R2 = R3 you can guess (homework) what the value of R1 shoud be ..
The circuit has to be followed by a buffer (ku=1) ..

Rgds,

Re: sinewave generator

You mean the connection as the schematic i attached below. please modify for me if any wrong. The output power is too low, how can i improve ? the output waveform is shift to negative, how can i shift to positive side?



Thanks...
