DIGITAL SWITCHING SIGNAL SEQUENCE FOR SWITCHING PURPOSES, DEVICE FOR INCLUDING RELATED DIGITAL SWITCHING SIGNAL SEQUENCE INTO DIGITAL INFORMATION AUDIO SIGNAL AND DEVICE FOR RECEIVING INFORMATION SIGNAL SUPPLIED WITH SWITCHING SIGNAL SEQUENCE Russian patent published in 2017 - IPC G10L19/00 H04N5/08

Abstract RU 2633108 C2

FIELD: radio engineering, communication.

SUBSTANCE: digital switching signal sequence is realized as a pre-digitized, high-pass filtered white noise signal of the predetermined duration T, with an upper cutoff frequency lying above the frequency, at which the loudness threshold characteristic in silence for human hearing has the greatest possible sensitivity. The switching signal sequence is used for switching purposes, for example switching between two information signals.

EFFECT: increasing the accuracy of detecting the digital switching signal sequence.
