    Hi again!

    I'd like to build a simple circuit that will invert any signal I put into it.

    Here are some graphic examples of exactly what I'm after:
    Input:

    Output:

    Input:
    [​IMG]

    Output;
    [​IMG]

    Can anyone make any suggestions on how I can do this?

    Use an inverting operational amplifier.
    A purely passive circuit is not possible. Therefore I will change the title of this thread.

    Inverting amplifier (Google it)

    (Actually, you could *almost* do it with a transformer, but it would be limited in bandwidth and you would lose any DC offset.)

    Passively? No, I can't think of a thing.
