tf2latc
Transfer function to lattice filter conversion.
[k,v] = tf2latc(num,den) k = tf2latc(1,den) [k,v] = tf2latc(1,den) k = tf2latc(num)
[k,v] = tf2latc(num,den)
finds the lattice parameters k and the ladder parameters v for an IIR (ARMA) lattice-ladder filter, normalized by den(1). Note that an error will be generated if any poles of the transfer function lie on the unit circle.
k = tf2latc(1,den)
finds the lattice parameters k for an IIR all-pole (AR) lattice filter.
[k,v] = tf2latc(1,den)
returns a scalar ladder coefficient v.
k = tf2latc(num)
finds the lattice parameters k for an FIR (MA) lattice filter, normalized by num(1).
The function latc2tf is the inverse of tf2latc.
