Hello community I'm Isaac. I'm dealing with some questions about the interpretation of sampling rate and bandwidth in a USRP source block.
What I understand is if I work with an USRP N210, my ADC works with a 100MS/s. If I use a Gigabit Ethernet and a data type of 16bits, I could receive in my host up to 25MS/s with a bandwidth of 20MHz. https://kb.ettus.com/About_USRP_Bandwidths_and_Sampling_Rates My questions are: 1. If I can receive up to 25MS/s on my host, why my bandwidth is 20MHz? I think It is up to 12.5MHz according to Nyquist. 2. Why is the sample rate value in the usrp source block equal to the bandwidth I observe? I think this bandwidth should be the half according to Nyquist too. https://wiki.gnuradio.org/index.php/USRP_Source I appreciate any help to clarify this concepts Regards Isaac T.
