... located one by one. 4. FASTER SEARCH ALGORITHM The study of LSF vectors indicates that there is a strong cor- relation between the LSFs of successive frames and that the change from one LSF vector ... distinct intervals, each containing only one odd and one even-indexed LSF, thus avoiding the zero crossing search. Another approach to compute LSFs based on split Levinson algori...
