I don't know the answer to that, but it seems to me that your example
has a DC bias. If we define origo ("zero") to the middle then the
signal would probably vary between 128 and -128, or 32 and -32. (Or if
you define origo ("zero") to be all bits=zero then 128 would be the
middle (silence), and the signal would vary between 256 and 0, or 160
and 96.) Or perhaps I misunderstood you completely. :P
