[Discuss-gnuradio] Data Rate

2006-03-10 Thread joe j
Hi All,    (sound stupid but...) Will the mux setup change the sample rate?  For instance:    I have 2 signals hooked up to RxA and RxB (2 diff. Rx basic daughterboards) and collecting data:    set_mux(gru.hexint(0x32103210)) be collecting less data per second than set_mux(gru.hexint(0x20202

Thanks alot Martin, for detailed explanation in the relationship of complex numbers with signals.  :) the output is a complex signal with amplitude=amp1*amp2 and phase=phase1-phase2To everyone, In regards to the mux question posted, something.set_mux(gr.hexint(0x32103210)), the block diagram of the

Hi Everyone,     I have two sets of data collected from the usrp board and now I'm trying to subtract the angle of the first data to the angle of the second data.  I was thinking to use gr.complex_to_arg() to get the angle values from both data then just subtract one from the other, but now I don
