Umer, You have a filter with a sample rate of 1.7GHz. This is obviously incorrect. Your filter must operate at the baseband rate; in the case of USRP2 with decimation 16, as you have it set up, the filter will operate at 100Msps/16=6.25Msps. The filter cutoff frequencies must be similarly relative to the baseband frequency, not absolute -- if you are tuned to 850MHz and want a cutoff at 850.4MHz, you would specify a cutoff frequency of 400kHz.
Additionally, did you really mean to use the USRP2 source? The old USRP2 source has been deprecated in favor of UHD for a very long time. --n On Mon, Jul 2, 2012 at 6:19 AM, <umer.rabb...@bt.com> wrote: > I have attached my GRC file with this email.
