Abstract
We calculate dynamical entropies from experimental data produced by a Schmitt trigger subjected to noise and a periodic forcing. Both input and output signals are converted to binary sequences. Conditional and Kullback entropies exhibit extrema for certain values of noise intensity. These extrema can be interpreted and will be related to the synchronization effect of switching events induced by external periodic bias.Keywords
