States from CIC filter
integerstates = int(hm.states)
integerstates = int(hm.states) returns
the states of a CIC filter in matrix form, rather than as the native
An important point about
int is that it quantizes
the state values to the smallest number of bits possible while maintaining
the values accurately.
For many users, the states of multirate filters are most useful as a matrix, but the CIC filters store the states as objects. Here is how you get the states from you CIC filter as a matrix.
hm = mfilt.cicinterp; hs = hm.states; % Returns a FILTSTATES.CIC object hs. states = int(hs); % Convert object hs to a signed integer matrix.
After using int to convert the states object to a matrix, here is what you get.
hm.states ans = Integrator: [2x1 States] Comb: [2x1 States]
After the conversion and assigning the states to
states states = 0 0 0 0
