Get fixed-point word and fraction lengths
[
returns all the word lengths and fraction lengths of the fixed-point sections and
the output of the CIC filter System objects, WLs
, FLs
] = getFixedPointInfo(cicObj
,nt
)dsp.CICDecimator
and dsp.CICInterpolator
, based on the input numeric type,
nt
. For locked objects or when the
FixedPointDataType
property of the unlocked CIC filter
object is set to 'Specify word and fraction lengths'
, the input
numeric type argument, nt
, is optional.
