dear all,
I've a question that i need an answer for it and IF U CAN, attached with it a site that can confirm your answer about it,
in FSK modulation, if the input digital bit (baud) rate was 64kbps, on what bases I should choose f1 and f2 that will be used for wireless transmission?
Is there's any relation between the input bit rate and the frequency used for modulation (f1 and f2) ?
and if f1 and f1 should be so high, by how much with respect of the input bit rate (baud rate)?
plz try to make ur answer confirmed with any site, IF U CAN, but if u can't it's ok,
I hope any one to answer me
thanks in advance

in FSK the seperation between frequencies must be greater than 1/2Ts. where Ts is the symbol ( or bit in binary) rate. it is MSK that has the minimum seperation between carriers i.e. 1/2Ts.
