DIGITAL SWITCHING SIGNAL SEQUENCE FOR SWITCHING PURPOSES, APPARATUS FOR INCLUDING SAID DIGITAL SWITCHING SIGNAL SEQUENCE IN A DIGITAL AUDIO INFORMATION SIGNAL, AND APPARATUS FOR RECEIVING THE INFORMATION SIGNAL PROVIDED WITH THE SWITCHING SIGNAL SEQUENCE.

摘要

A digital switching signal sequence is suggested, this switching signal sequence being realized as a previously digitized, highpass filtered white noise signal of a predetermined length T, with a highpass cut-off frequency which lies above the frequency where the loudness threshold characteristic in silence of the human hearing has its highest sensitivity, if possible (Fig. 5). The switching signal sequence is employed for switching purposes (206), e.g. for switching between two information signals (201, 207). Fig. 2.
