    Hi all
    I was wondering is there a way to develop a circuit that mirrors only negative voltages to the positive half but with the positive half it remains the same? So I have input signal that can be a positive or negative voltage, if it's positive I want it to just pass to the output, and if it's negative the magnitude of the voltage is retained but it is inverted to a positive voltage if that makes sense. Any guidance or tips would be greatly appreciated.

    Kind Regards

    Google "precision full wave rectifier."
