I appracite you could tell me what is the meaning of following paramaters:
@param audio_rate: sample rate of audio stream, >= 16k
@type audio_rate: integer
@param quad_rate: sample rate of output stream
@type quad_rate: integer
@param tau: preemphasis time constant (default 75e-6)
@type tau: float
@param max_dev: maximum deviation in Hz (default 75e3)
@type max_dev: float
I try to change the max_dev from 10 to 1000,and give it to a usrp source as
baseband signal,
but, the bandwith on spectrum analyize don not change.How to change
deviation of a fm signal?
