Hi,

 

You can look into "Multirate Signal Processing" by Fedrick Harris for more details regarding CIC filter, decimators,etc..

Thanks

Hello everyone:
  You see in theory there should be a low-pass filter after ADC for eliminating the image. Also after DDC there should also be a
filter. But in USRP there are not such things. So do the cic filter and half band filter implement that function besides decimation?
