frequency modulation

I've been looking into how synthesisers work; frequency modulation, phase distortion, etc. Wikipedia has been good.

During my search for components and a better understanding of the technology I came across this 'function generator' at Maplin (quite expensive). Check out the discription of possible applications.

To change non-hearable frequencies and vibrations into audio signal and also for scanning through the spectrum of input this might be the technology we need to investigate further.
