Is saying "GFSK" self-defining? Are there variations on the techniques to reduce occupied bandwidth?
Would this spectrum signature be such that a simple FSK receiver cannot demodulate a GFSK signal?
And vice-versa, GFSK receiver demodulating an FSK transmission?
(Assuming one can adjust/fiddle with the receiver bandwidth, modulation index, etc. for the FSK system but the GFSK system cannot be altered)
stevech bump?

What is the BT of the Gauss filter? of bigger than about 0.4 it will work both ways (perhaps from 0.3).
The reason for using Gauss is that the fourier transform of a gsuss signal is a gauss signal, so the sidebands cansel each other out.(to some degree)
stevech thanks ... "BT" is?
try to google somthing like GMSK BT then there will be some good hits (some will be for GFSK aswell) the G and BT part is the same for GMSK and GFSK.
