    I'm really useless at analog circuitry, so any help is appreciated.

    I have:

    input P0 != GND
    input P >= P0
    constant A < 1

    I would like:

    output P* = A (P - P0) + P0

    Can and should I use an op-amp for this, or is that overkill?

    I know if P0 = GND, then I can just use a resistor to "multiply" by A,
    but no such luck.

    Thank you for reading.

    Thank you. It is much easier than I expected. /YR
