multistage filter design

Hello,

I'm working on the design of digital FIR filter with following specification:

fpass=0.015;
fstop=0.0225;
rpass=0.001;
rstop=0.0001;

since the single stage filter has high order(tried kaiser window and equiripple method), I have to design a multistage filter. what method may be best method for this specification? Does Matlab have any other code except "multistage" for multistage design, as "multistage" designs only equiripple FIR filter.

Regards
Yadav Shrestha

use matlab signal processing fft program or use the filter()
