Re: [Discuss-gnuradio] Sampling Rate

[Ben Hilburn]

In the same way that GNU Radio uses complex samples, USRPs also deliver complex baseband samples; thus, 25 MSPs of complex baseband gives you 25 MHz of bandwidth.

Cheers,

Ben

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.
