Although you are approximately right in many parts of this discussion,
you are wrong on the cost of the CPU flags to round twards zero. The
cost is nil. BTW: adding just a small DC bias won't work
if I have IIR high pass like
structure, or am I wrong ?
You have to apply the small offset at 'strategic places'. For an IIR
this is at the summing node, to the value that gets stored into the
filter's delay line. In other words, inside the feedback loop.
