fir filter design using matlab

[lakshmikalyani]

hi
my specifications are passband frequencies are 200 and 315 for a band pass filter
i have to design a filter bank with a range of frequencies. this is first frequency band
i have to design a fir filter bank form 200 to 7500 hz.
my sampling frequency should be more than 15000 i took it as 16000. the stop band frequency must be 5% more than passbands if i do like that i am getting highest order
pleas help me to resolve the problem
i need to get lower order to get the response.
