Since each halfband filter section decimates by 2, the total
decimation through the halfband filter is given by:
where N = Number of Halfband Filters Selected (1 - 5).

NOTE: If 14 input bits are not needed, the gain adjust can be in-
creased by one for each bit that the input is shifted down at the
input. For example, if only 12 bits are needed, an offset range of
24dB is possible for a decimation of 24.
