Abstract :
In this article, we use some spectral properties of polynomials presented in [1] and map an auto-correlation sequence to a set of Line Spectral Frequencies(LSFs) and reflection coefficients. This novel characterization of an autocorrelation sequence is used to obtain a lattice structure of a Linear-Phase(LP) FIR filter.
