Кривенко // Радиоэлектроника и молодежь в ХХI веке : материалы 16-го Междунар. молодеж. форума, 17–19 апр. 2012 г. – Харьков : ХНУРЭ, 2012. – Т. 3. – С. 183–184.https://openarchive.nure.ua/handle/document/22473The given work is devoted to the modem problems of protecting audio information with the help of nonlinear effects appearing when ultrasound wave spread. Nonlinearity changes a waveform because the wavespeed can depend on the stress level, so that the high-stress parts at the peaks of a wave move at a different speed than those at low stress (some effects make the speed higher and some lower).otherConference proceedings
