  • Abstract
    The standard first-order preemphasis approach used in linear prediction analysis results in an undesirable low-frequency boost in the synthesis spectrum. A solution is obtained by mismatching the preemphasis and postemphasis factors or by using a particular second-order preemphasis filter.
