FM Radio receiver LabVIEW VIs
Ok so I forgot to actually include the VIs in the post back in June (http://cr.jamesyxu.com/?p=122), some people have been asking for it, so I will post the images here…. all files are expected to be open via SVN later though, so dont worry…
So we can see that it uses eh.. IQ Data for demodulation.. which is described in the older article. Butterworth filter is also used, and the settings are nearer the top left corner
Basically the most important part would be the demodulator in the middle there.. The other parts are basically to filter the signal, and then to make sure the play back will be at a normal speed (by padding the output to the correct sampling rate).
I think this is about it?
