Hi Jason, Please go through this, http://gnuradio.org/redmine/projects/gnuradio/wiki/TutorialsCoreConcepts#Sampling-rates Try 1. Varying USRP sample rate and observe the output using FFT sink 2. In the flowgraph use an interpolator (rational resampler) just before your USRP sink, vary the inter

Hi Ali, the Nyquist bandwidth of a complex signal is equal to its sample rate. You can set the sample rate of your usrp_sink during flowgraph construction in the properties dialog, using stream tags, using asynchronous messages or simple method calls: http://gnuradio.org/doc/doxygen/page_uhd.html

Hi , Can anyone kindly tell that how i can vary the bandwidth of my transmitted signal in GRC??I am using B210 which has a instantaneous bandwidth of 56MHz.. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinf
