title: Mathematical decomposition of the round window potential.
abstract: We present an algorithm called the median transform which can be used to decompose the round window auditory potential into AC and DC components. The first of these is identified with the cochlear microphonic, and the second with the combined summating and compound action potentials. Elsewhere in this volume, the algorithm is employed as an intermediate step in obtaining the instantaneous frequency of the CM. Since the algorithm is easily implemented and operates entirely in the time domain, it may prove useful to clinicians as well as researchers.
