I am confused about the sample rate in GRC...if i am RXing a signal by
USRP
B210 at 2.4 GHz then the sample rate should be 4.8GHz??But USRP B210
uses a
direct conversion RX and shifts the signal to 0Hz,so what should be the
criteria for setting the sample rate?
Another option could be ton set it double the channel
bandwidth??i.e.(56*2)MHz

If you want 1e6 Hz (1MHz) of receive bandwidth at a center frequency of
2.4e9 Hz (2.4GHz) then you just set the center frequency to 2.4e9 and
sample rate to 1e6 in the UHD source block in GRC.
