Examples
-1) FIR filter -k1 = [1/2 1/2 1/4]; -[num1,den1] = latc2tf(k1); |  |  |
Convert lattice filter parameters to transfer function coefficients
[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
