Hi  
I am trying to generate an LFM signal using GNU radio and USRP but I am  
not sure about the interpretation of Sensitivity parameter in Freq  
Modulation block that what are its units, what is the possible range of  
values and how does it effect the characteristics of modulated  
waveform/signal etc.?
