Hi, I'm getting confused with the concept of "Sampling rate" to set the UHD:USRP Source and other blocks from the gnuradio-companion. If I'm still right, the sampling rate must be at least the double of the operating frequency. But I can see some working applications when this Nyquist theory is not respected. How come?
GnuRadio uses complex (I & Q) samples. This results in twice the data per sample, satisfying the Nyquest criterion. @(^.^)@ Ed
