Hi

When I specify a particular receiver decimation rate
for the USRP2, the task of decimating is presumably
split up between the CIC and two half-band filters.
My question is how is the task split up,
and where in the code does this happen?

If the requested decimation rate is a multiple of four, we use the two halfband filters, and the rest is CIC. If it is only a multiple of two, we use one halfband filter and the rest in CIC. If it is an odd number, we use only CIC.
