On line spectral frequencies
2003 (English)In: IEEE Signal Processing Letters, ISSN 1070-9908, E-ISSN 1558-2361, Vol. 10, no 3, 75-77 p.Article in journal (Refereed) Published
The commonly used line spectral frequencies form the roots of symmetric and antisymmetric polynomials constructed from a linear predictor. In this letter, we provide a new, simpler proof that the symmetric and antisymmetric polynomials can be regarded as optimal constrained predictors that correspond to predicting from the low-pass and high-pass filtered signal, respectively.
