[USRP-users] DDC's Filters in B210

Altuğ,

per channel, there's 2 half-bands and 1 CIC. The rule is: We try and
enable as many half-bands as possible, the rest is done by CIC. So, any
ratio of sample_rate to master_clock_rate that is divisible by 4 has 2
half-bands, any other even ratio has 1 half-band, and the remainder is
done in the CIC.

Cheers,
Martin
