In the case of an FSK, the discrete frequency changes of a carrier signal bears responsibility of transmitting digital information. Thus, the output of an FSK modulated wave is high in frequency for a binary high input, and low in frequency for a binary low output.

No problem. Great to know that it was useful.

the demodulator needs some rework, i changed the air/wire interface with an OpAmp and provide a recgangular wave form, anyway the base frequency is still available and should work for a demodulator. But as you can see its not. http://everycircuit.com/circuit/5563465012609024

Pretty cool, Hurz. The modulator is smoothened out much better than the original.
