Abstract: The present invention relates to signal processing and, more particularly, to the use of local signal behavior parameters for the description of signals within sampling windows. Improved accuracy in local signal representation is achievable by using appropriate windowing functions within the local sampling windows where such windowing functions approximately compensate for truncation errors arising in finite representations of the exact signal. Other embodiments include windowing functions approximately compensating for the expected noise values that tend to corrupt the signal. Improved accuracy in local signal representations employing chromatic derivatives are described.
