Ina tukuna e tatou he tohu, ahakoa he tohu whatu, he tohu hiko, he tohu ahokore ranei, mena ka tukuna tika, ka ngawari te raruraru o te tohu e te haruru, he uaua ki te whiwhi korero tika i te pito whiwhi. Hei whakapai ake i te kaha aukati o te punaha, ka taea te mohio ma te whakarereke i te tohu. Ka taea hoki e te whakarereketanga te whakamahi pai ake i nga hongere, na reira ka pa nui ki te pai me te pono o nga punaha whakawhitiwhiti korero.
Ko te whakarereketanga koki e whakaahuatia ana i raro nei mo nga tohu tairitenga.
E toru nga tawhā o te kawe sinusoidal:te kaha kaha, te auau, me te wahanga. Ka taea e taatau te utaina nga korero o te tohu whakarereke ehara i te mea anake i roto i te huringa kaha o te kaikawe engari i roto ano hoki i te huringa o te waa me te huringa o te kaikawe. I te wa o te whakarereketanga, mena he rereke te auau o te kaikawe ki te tohu whakarereke, ka kiia ko te huringa auau, te whakarereketanga auau ranei (FM); Mena he rereke te waahanga o te kaikawe ki te tohu whakarereke, ka kiia ko te whakarereketanga o te waahanga, te whakarereketanga o te waahanga ranei (PM) I roto i enei momo tukanga whakarereke e rua, ka noho tonu te kaha o te kaikawe, ka whakaatuhia te huringa o te auau me te waahanga ko te huringa o te wahanga inamata o te kaikawe. Na reira, ko te FM me te whakarereketanga wahanga e kiia ana ko te whakarereke koki.
Te rereketangai waenga i te whakarereketanga koki me te huringa kaha kaha, ko te awhi tohu whakahuri kua kore ake i te nekehanga raina o te awhi tohu whakarereke taketake, engari ko te hurihanga kore-raina o te awhiowhio, ka puta nga waahanga auau hou rereke mai i te nekehanga awhi, no reira ka kiia hoki. whakanekehanga ahokore.
FM me te PMe whakamahia nuitia ana i roto i nga punaha korero. Kei te whakamahia nuitia te FM i roto i te haapurororaa puoro tino pono, te tuku tohu tangi pouaka whakaata, te whakawhitiwhiti amiorangi, me nga punaha waea pūkoro. I tua atu i te whakamahi tika mo te tuku, ka whakamahia ano te PM hei whakawhiti mo te whakaputa autaki i nga tohu FM. He hononga tata i waenga i te huringa auau me te whakarereketanga o te wahanga.
Ka whakatauritea ki te hangarau whakarereke amplitude, Ko te tino painga o te whakarereketanga koki ko tana mahi haruru nui. Heoi ano, he hua, he mate. Ko te utu mo te whiwhi i tenei painga ko te koki koki e noho ana i te whanui whanui atu i te tohu huringa amplitude.
Kei runga ake nei ko te whakamaramatanga o nga tohu matauranga mo te whakarereketanga kore (whakarereke koki) i kawea mai a HDV photoelectric Technology Co., Ltd. Ko Shenzhen HDV photoelectric Technology Co., Ltd. te nuinga o te kaihanga o nga hua korero. I tenei wa, ko nga taputapu i hangaia e hipoki ana i teONU raupapa, raupapa kōwae whatu, raupapa OLT, araupapa transceiver. Ka taea e matou te whakarato ratonga motuhake mo nga ahuatanga rereke. Tena koekorero.
