Hi everyone...
I am getting confused about the use of the parameter of sampling rate in GNU RADIO.

I really need  to understand the sampling rate of the uhd sink and source and  the sampling rate of the blocks in the flow graph and how to choose those sampling rates.

Thanks a lot for you help!!

Sample rate is a fundamental parameter of digital signal processing. Try an introductory DSP textbook, or the following articles:

http://en.wikipedia.org/wiki/Discrete_signal

http://en.wikipedia.org/wiki/Sampling_rate

http://en.wikipedia.org/wiki/Nyquist%E2%80%93Shannon_sampling_theorem

http://en.wikipedia.org/wiki/Sampling_(signal_processing)

http://en.wikipedia.org/wiki/Aliasing

Without a basic understanding of sampling theory or DSP you will have difficulty progressing with Gnuradio.
