Marcus, any PAM signal with symbol rate R can be transmitted using bandwidth R/2
(essentially a sinc pulse; this is the case when you put 0 as the roll-off factor of an RRC). I thought your comment was not specifically for CPFSK, but general transmission schemes thus my clarification. If it is specific for CPFSK then kindly disregard the above.
