| | 136 | Here, the "Signal Source" generates samples for a 1 MHz cosine wave at the flowgraph sample rate, in this case 10 MHz. The samples then go into a "UHD Sink". The "UHD Sink" is what takes the signal samples generated in GNU radio and sends them to the USRP for transmission. Samples are generated |
