Hi guys
I need to convert a sine wave signal 0 - 3V into -9 to +9 sine wave. I think I need to use Opamp but I am not able to figure out circuit.
How can I do it?

One of many ways...
|\\ INPUT o------------|+\\ | \\ | \\ | |------+--o OUTPUT | / | | / |
+12V o--6.66K--+---|-/ | | |/ | | | +------5K-------+ | | 1.1765K | | GND...Jim Thompson

** Groper Alert !
** Use a capacitor to remove the DC offset from the original sine wave - gives a sine wave that has +/- 1.5 volt peaks.
Follow that with a amplifier stage with gain of 6.

Very interesting stuff.
