[ferret_users] lsl_lowpass

Hi users,
	This is actually not a FERRET question but somebody who familiar
lsl_lowpass function may be able to help.
       I would like to retain a particular frequency in a monthly time
series, say 7-9 year periodicity.  For this purpose I constructed two
seperately filtered time series using lsl_lowpass function
filt1=lsl_lowpass(A, 108,108) 
to retain 7-9 year periodicity filt1 is subtracted from filt2
Does this yield good results?
