DEVICE FOR DETERMINING INFORMATION ON SIMILARITY, METHOD FOR DETERMINING INFORMATION ON SIMILARITY, DEVICE FOR DETERMINING INFORMATION ON AUTOCORRELATION, DEVICE FOR DETERMINING INFORMATION ON MUTUAL CORRELATION AND COMPUTER PROGRAM

摘要

An apparatus for determining a similarity information on the basis of one or more input signals is configured to determine a zero crossing information describing a number of zero crossings in a respective portion for a plurality of portions of at least one of the one or more input signals. The apparatus is configured to perform a comparison on the basis of the zero crossing information, in order to determine the similarity information. A method for determining a similarity information and a computer program are also described. Moreover, an apparatus for determining an autocorrelation information and an apparatus for determining a cross-correlation information are based on similar considerations.
