Preprints are manuscripts made publicly available before they have been submitted for formal peer review and publication. They might contain new research findings or data. Preprints can be a draft or final version of an author's research but must not have been accepted for publication at the time of submission.
The amount of randomness in a signal generated
by physical or non-physical process can reveal important information about that
process. In this direction, the
present work proposes to use the disentropy of the autocorrelation function as
a measure of randomness. Examples using noisy and chaotic signals, economic and
biological data are shown.
