Can you explain this a little more?  It's probably clear to many, but 
not me. :-)  I think of 'channel' as the RF channel, but this is used 
differently. A demod channel as opposed to what other sorts of channels?

Also, since an fft/ifft change over between frequency and time is the 
norm in SDRs, why does it matter at what point processing is performed?

Not doubting, wanting to understand.  Tnx es 73.
