Te matauranga hua

He ara iahiko te wahanga o te ngaru kawe e te tohu whakahuri. E rua nga momo whakarereketanga o te wahanga ngaru hiko: te whakarereketanga o te wahanga tika me te whakarereketanga o te wahanga autaki. Ko te maataapono o te whakarereketanga o te wahanga tika ko te whakamahi i te tohu whakarereke ki te huri tika i nga tawhā o te karu whakaruruhau, kia taea ai e te tohu kawe i roto i te resonant loop ki te whakaputa i te nekehanga o te wahanga me te hanga i te ngaru huringa wahanga; Ko te tikanga whakarerekētanga wahanga autaki i te tuatahi ka whakarereke i te kaha kaha o te ngaru whakahuri, katahi ka huri i te huringa tiwerawera ki te huringa wahanga, kia tutuki ai te huringa wahanga. I hangaia tenei tikanga e Armstrong i te tau 1933, i kiia ko Armstrong modulation method

Ko te whakanekehanga wahanga ngaruiti e whakahaerehia ana e te hiko he whatunga tauranga-rua hei whakarato i te rereketanga o te wahanga i waenga i te whakaputanga me nga tohu whakauru ka taea te whakahaere e te tohu mana (te nuinga he ngaohiko piro DC). Ko te nui o te nekehanga o te wahanga ka rereke tonu me te tohu mana, i te uara motuhake ranei. E kiia ana ko nga huringa wahanga tairitenga me nga huringa wahanga matihiko. Ko te waahanga whakarereke he waahanga-rua-rua te whakaneke i te whakahuri i roto i te punaha korero ngaruiti, e whakamahi ana i nga ngaru tapawha tonu hei whakarereke i te tohu kawe. Ka taea te wehewehe i te wahanga ngaru o te ngaru ki te whakarereketanga o te wahanga tika me te whakarereketanga o te wahanga autaki. Ma te whakamahi i te hononga o te koki ngaru ngaru he mea nui ki te auau inamata, ka taea te huri i te ngaru whakarereke hei ngaru whakahuri i te waahanga (he rereke ranei). Ko te ara iahiko whakahurihuri wahanga tika e whakamahia nuitia ana ko te varactor diode phase modulator. He uaua ake te ara iahiko whakanekehanga wahanga autaki i te ara iahiko whakanekehanga wahanga tika. Ko tana maataapono ko tetahi ara o te tohu kaikawe ka nekehia e te 90° whakanekehanga wahanga ka uru ki roto i te taurite amplitude-modulator ki te pehi i te huringa amplitude o te kawe. I muri i te attenuation tika, ka honoa te tohu kua whiwhi ki tetahi atu ara o te kaikawe ki te whakaputa i te tohu amplitude-modulating. Ko te ahua o tenei ara iahiko he nui te pumau, engari ko te nekehanga o te wahanga kaore e nui rawa (he iti iho i te 15°), he korikori kino ranei. He maha nga wa e whakamahia ana te modulator waahanga ngawari i roto i nga kaiwhakaputa haapurororaa FM.
