    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...

    INPUT o------------|+\
    | \
    | \
    | |------+--o OUTPUT
    | / |
    | / |
    +12V o--6.66K--+---|-/ |
    | |/ |
    | |

    Ooops..not Av=9...Its Av=6
    ...and the Mars probe bumps into a rock never able to go into reverse..

    ** 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.

    Congrats, Jim, it's nice to post drawings that become a

    Very interesting stuff.

    What "... better things to do with (your) time" ??
