Also, note that if you scale the whole set of values (0.099046,
0.296516, 1.052691, 0.1848) by the same amount, it's equivalent to
scaling WHITE by that amount. So you may be able to make some of those
coefficients easier to deal with at the same time you do the scaling.
If you scale the whole set the same, the filter frequency response will
stay the same and only the amplitude will change. Don't change the
coefficients applied to b0, b1, b2 or it will change the frequency
response. Beware that you will NEED to keep b0, especially, as a 16
bit number at least. 8 bits will almost certainly NOT be enough for
it, especially as you scale the input smaller. (Welcome to the world
of digital filters with poles at a tiny fraction of the sample
frequency--poles close to z=1.)
Cheers,
Tom
