This article is a useful one I’ve studied to understand FM demodulation
In the block of code that implements (albeit I haven’t tried to run it
because it’s not made to run with a USRP, it’s more pedagogical), to
demodulate two frequencies, it averages them and then centers them
My guess is that this is the frequency that serves as a “0” post
demodulation. Ie by reading frequency 5.75e6, you are reading the 0
frequency. But I’m not sure.
If this is the case, if I wanted to implement something similar using
USRP and TVRX, is there a similar “center” that I need to use? Is it
or is it simply 0hz?
I’ve attached the code.
