filtstates - Filter states

Syntax

Hs = filtstates.structure(input1,...)

Description

Hs = filtstates.structure(input1,...) returns a filter states object Hs, which contains the filter states.

You can extract a filtstates object from the states property of an object with

Hd = dfilt.df1
Hs = Hd.states

or, for an mfilt object in the Filter Design Toolbox product, with

Hm = mfilt.cicdecim
Hs = Hm.states

Structures

Structures for filtstates specify the type of filter structure. Available types of structures for filtstates are shown below.

filtstates.structure	Description
filtstates.dfiir	filtstates for IIR direct-form I filters (dfilt.df1, dfilt.df1t, dfilt.df1sos, and dfilt.df1tsos)
filtstates.cic	filtstates for cascaded integrator comb filters. (Available only with Filter Design Toolbox and Fixed-Point Toolbox products.)

Refer to the particular filtstates.structure reference page or use the syntax help filtstates.structure at the MATLAB prompt for more information.
