I mean... the sampling rate of the uhd sink and source what refers to...? I've since in some documents that if you are transmitting , you have to take in account that the DAC for output  works at 128 M/s and the sample rate for the  UHD sink block has to be determined somewhow from that.
In the same way the ADC for reception works at 64 M/s and the sampling rate for the UHD source block has to be determined somehow from that 64 M/s .

I just want to make simple transmission and reception.

Am I wrong? or I am understanding not really good what I am reading about this. Thanks in advance.

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:

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