摘要

1. The sequence of digital switching signals for switching purposes, and is composed of a sequence of predetermined digitized filtered upper filter a white noise signal frequencies predetermined duration T, having an upper cutoff frequency that is higher than the frequency (1005) on which the characteristic values ​​in the threshold volume silence (1001) to the human ear has its highest chuvstvitelnost.2. Switching sequence of digital signals according to claim 1, characterized in that the upper cutoff frequency is in the frequency range between 4 and 10 kGts.3. Switching sequence of digital signals according to claim 2, characterized in that the upper cutoff frequency is in the frequency range between 6 and 8 kGts.4. An apparatus for switching the switching sequence of digital signals according to claim 1, 2 or 3, in the digital information signal is provided with a first input (100) for receiving the information signal and a second input for receiving a sequence of switching signals, wherein the apparatus is further provided with circuitry (105) combining signals for combining the information signal and the switching sequence signalov.5. Apparatus according to claim 4, characterized in that the signal combining circuit is further configured to include a second sequence (601) of the switching signals in the information signal, wherein the second sequence of switching signals inverted relative to the first sequence (600) of the switching signal, both the switching sequence signals are included in the information signal with preliminary
