Conversion of transfer function to lattice filter.
Syntax
[k,v] = tf2latc(b,a) k = tf2latc(1,a) [k,v] = tf2latc(1,a) k = tf2latc(b)
Description
[k,v] = tf2latc(b,a)
finds the lattice parameters k and the ladder parameters v for an IIR (ARMA) lattice-ladder filter, normalized by a(1). Note that an error is generated if one or more of the lattice parameters are exactly equal to 1.
k = tf2latc(1,a)
finds the lattice parameters k for an IIR all-pole (AR) lattice filter.
[k,v] = tf2latc(1,a)
returns the scalar ladder coefficient at the correct position in vector v. All other elements of v are zero.
k = tf2latc(b)
finds the lattice parameters k for an FIR (MA) lattice filter, normalized by b(1).
