Hello,
The purpose of my study is the effect of (mechanical) vibrations of an antenna on the signal.
So let begin easy and let's say that a signal without antenna vibration is x(t) = a*sin(w1t)
Now if the antenna is vibrating, the signal becomes
x(t) = a*sin(w1t + deltaphi*sin(w2t))
With the "source block" it is not possible, you can just set a fixed frequency.
I tried also with "delay" block but without success.
Maybe I am blind and another block makes the job but I can't find it.
So I am trying to implement my own source block for this. In the different code examples that I have seen, I can't see anything related about "time" in the code. How can I add this kind of signal in GNU Radio ?
Any tips for this ?
Thanks,
Xavier
