my first questions about CIC filter input datatype limit in Matlab

Started by Unknown September 26, 2007
hi everyone,


when I use FDATools to design a CIC(cascade integrator comb)filter the
input datatype must be signed fix point. but after our sigma delta
modulator, the output is in double type. how could I transfer between
them in order to use CIC filter in Matlab simulink.

forgive me my poor expressions
and Thanks a lots
