[Discuss-gnuradio] Angle manipulation & other concerns

[joe j]

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't know if there is a way to put the modified angle back with the first data's magnitude.  Are there any existing functions to do this?

 

  My other concern is how the data is collected from the usrp board - I read the tutorial on how the mux works though I still don't understand it exactly.  So if I say something.set_mux(gru.hexint(0x32103210)), what does that really do?

 

Thanks,

JC
