latc2tfConvert lattice filter parameters to transfer function coefficientsCalling SequenceDescription
[num,den] = latc2tf(k,v)
Finds the transfer function of the IIR filter from the lattice
coefficients k and ladder coefficients v.
[num,den] = latc2tf(k,'iiroption')
Finds the transfer function of the allpass or allpole (specified by
the iiroption flag) IIR filter.
num = latc2tf(k,'firoption')
Finds the transfer function of the FIR filter from the lattice
coefficients k. The firoption flag specifies the type of the FIR
filter (can be 'min, 'max', or 'FIR')
Parameters:
k - double - vector
Lattice coefficients
Lattice coefficients for FIR/IIR filter. Can be real or complex.
v - double - vector
Ladder coefficients
Ladder coefficients for IIR filters. Can be real or complex.
iiroption - string flag - 'allpole', or 'allpass'
Specification of the type if IIR filter
firoption - string flag - 'min', 'max', or 'FIR' (default)
Speficication of the type of FIR filter
