Unipolar to Bipolar

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?

Summing amplifier Av=9 (Was 3Vpp changing to 18Vpp)
Signal + offset DC

One of many ways...

Ooops..not Av=9...Its Av=6

Don't believe it- the aged fart actually posted an ASCII schematic!!!!

** 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.

Oh Buggerit!! You got there before me.....

Congrats, Jim, it's nice to post drawings that become a
permanent part of the record.

Channel State Information, I assume. I've better things
to do with my time.

Very interesting stuff.
