    Hello! i am implementing a code to read the signal of an optical
    decoder joint to a motor . I don't know if before the codification of
    the position it is necessary to filter the signals from the encoder...
    does somebody know it?
    thanks in advance
    bye

    It depends on how "dirty" the signals are, so from your particular
    environment/layout/shielding!
    I would say: some simple filters won't hurt in any case...
