Nkwurịta okwu nke stress wave bụ usoro nke izipu na ịnata ozi site na iji usoro onye ọbịa n'onwe ya dị ka usoro nnyefe. Enwere ike iji usoro modulation omenala dị ka amplitude-shift keying (ASK), frequency-shift key (FSK), phase-shift koying (PSK), quadrature amplitude modulation (QAM), pulse-position modulation (PPM) na orthogonal frequency-division multiplexing (OFDM) maka nkwurịta okwu mkpọtụ. Ihe ịma aka iji ebili mmiri nrụgide dị ka onye na-ebu nkwurịta okwu bụ nnukwu mgbagwoju anya n'ihi mgbasa nke ọtụtụ ụzọ. E jiri ya tụnyere usoro nkwurịta okwu ndị ọzọ, ọ bụ nkwurịta Okwu a pụrụ ịdabere na ya maka ngwa pụrụ iche, dị ka n'ime ihe owuwu simenti, eriri igwu olulu mmiri, ihe owuwu pipeline na ihe ndị ọzọ.[1][2][3][4][5]
