I have been searching for some basic documentation describing the GRC components without much luck. For instance, I can't find an explanation of why multiplying with a 50ksps sine wave specified to have zero frequency and an amplitude of 1 has any effect, though I have seen it in several examples e

Hi, Does anyone has some discription about the two programs usrp_fft.py and usrp_oscope.py? I try to search in the archive but didn't find any basic discriptions. For example, I'm using digital-bert benchmark_tx.py to transmit a sequence of 1's, which modulated by BPSK; on the other computer, I us

[Discuss-gnuradio] Basic questions relating to the USRP and the TV_RX board
