plot fsk

[Seube]

Hi all,

I would like to plot a simple FSK signal but the drawn signal does not fulfill my expectations:

- the amplitude should be constant and equal to a certain level. Here the frequency is not constant and increases for '1' symbols

- we should have one frequency for '1' symbol and another for '0'. the signal seems to be equal to zero for '1' symbols.

Where am I wrong ?

thanks !
