rc2poly() - Signal Processing
a = rc2poly(k) converts
the reflection coefficients k corresponding to
the lattice structure to the prediction filter polynomial a,
with a(1) = 1.
The output a is row vector of length length(k) + 1.[a,efinal] = rc2poly(k,r0) returns
the final prediction error efinal based on the
zero-lag autocorrelation, r0.
a = rc2poly(k)[a,efinal] = rc2poly(k,r0)
Equivalent Prediction Filter RepresentationOpen This Example
Consider a lattice IIR filter given by a set of reflection coefficients. Find its equivalent prediction filter representation.
k = [0.3090 0.9800 0.0031 0.0082 -0.0082];
a = rc2poly(k)
1.0000 0.6148 0.9899 0.0000 0.0032 -0.0082
