He ngaru hiko auau-teitei te reera, nā tōna hononga pai, pērā i ngā ngaru hiko tuku iho (pērā i te reo irirangi me te pouaka whakaata), hei ngaru kawe hei tuku kōrero. Ko te tukanga uta kōrero ki runga i te reera ka kiia ko te whakarerekētanga, ā, ko te taputapu e mahi ana i tēnei tukanga ka kiia ko te whakarerekētanga. I roto i tēnei tukanga, ka mahi te reera hei kawe, ko te tohu auau-iti e tuku ana i ngā kōrero ka kiia ko te tohu whakarerekētanga.
Ko te whakarerekētanga reera e wehea ana kia rua ngā huarahi, arā, te whakarerekētanga ā-roto me te whakarerekētanga ā-waho. Te whakarerekētanga ā-roto: e pā ana ki te whakarerekētanga i roto i te tukanga o te wiri reera, arā, mā te whakarerekē i te tohu hei whakarerekē i ngā tawhā wiri o te reera, ā, ka pā ki ngā āhuatanga putanga o te reera. E rua ngā huarahi o te whakarerekētanga ā-roto: 1. Whakahaere tika i te pūhiko papu o te reera hei whakarerekē i te kaha o te putanga reera. Mā te whakamahi i te tohu hei whakahaere i te pūhiko reera, ka taea te whakahaere i te kaha putanga reera e te tohu. 2. Ka whakanohoia ngā huānga whakarerekētanga ki roto i te resonator, ā, ka whakahaerehia ngā āhuatanga ā-tinana o ēnei huānga whakarerekētanga e te tohu, kātahi ka whakarerekētia ngā tawhā o te resonator hei whakatutuki i te whakarerekētanga o te putanga reera. Ko te painga o te whakarerekētanga ā-roto ko te teitei o te whai huatanga whakarerekētanga, engari ko te ngoikoretanga ko te mea kei roto i te kōhao te modulator, ka whakanui ake i te ngaronga i roto i te kōhao, ka whakaiti i te mana putanga, ā, ka whakawhāitihia hoki te whānui o te modulator e te passband o te resonator. Te whakarerekētanga o waho: ko te tikanga, i muri i te hanganga o te taiaho, ka whakanohoia te whakarerekētanga ki te ara whatu i waho o te taiaho, ā, ka whakarerekētia ngā āhuatanga ā-tinana o te whakarerekētanga me te tohu whakarerekētanga, ā, ina haere te taiaho mā roto i te whakarerekētanga, ka whakarerekētia tētahi tawhā o te ngaru mārama. Ko ngā painga o te whakarerekētanga o waho ko te kore e pāngia te mana putanga o te taiaho, ā, kāore te whānui o te pūmana e herea e te whānuitanga o te resonator. Ko te ngoikoretanga ko te iti o te whai huatanga o te whakarerekētanga.
Ka taea te wehewehe i te whakarerekētanga taiaho ki te whakarerekētanga whānui, te whakarerekētanga auau, te whakarerekētanga ā-wāhanga me te whakarerekētanga kaha, e ai ki ōna āhuatanga whakarerekētanga. 1, whakarerekētanga whānui: ko te whakarerekētanga whānui ko te wiri e huri ai te whānui o te kaikawe me te ture o te tohu whakarerekētia. 2, whakarerekētanga auau: hei whakarerekē i te tohu hei whakarerekē i te auau o te wiri taiaho. 3, whakarerekētanga ā-wāhanga: hei whakarerekē i te tohu hei whakarerekē i te ā-wāhanga o te taiaho wiri taiaho.
Kaiwhakarerekētanga kaha hiko-whatu
Ko te kaupapa o te whakarerekētanga kaha hiko-whatu ko te whakatutuki i te whakarerekētanga kaha e ai ki te kaupapa pokanoa o te mārama pōrari mā te whakamahi i te pānga hiko-whatu o te tioata. Ko te pānga hiko-whatu o te tioata e pā ana ki te āhuatanga e huri ai te taupū whakaata o te tioata i raro i te mahi a te mara hiko o waho, ka hua ake he rerekētanga ā-wāhanga i waenga i te mārama e haere ana i roto i te tioata i ngā ahunga pōrari rerekē, kia rerekē ai te āhua pōrari o te mārama.
Kaiwhakarerekētanga wāhanga hiko-whatu
Te mātāpono whakarerekētanga ā-wāhanga hiko-whatu: ka whakarerekētia te koki ā-wāhanga o te wiri taiaho e te ture whakarerekētanga tohu.
Haunga ngā whakarerekētanga kaha hiko-whatu me te whakarerekētanga ā-wāhanga hiko-whatu kua whakahuatia ake nei, he maha ngā momo whakarerekētanga taiaho, pērā i te whakarerekētanga hiko-whatu whakawhiti, te whakarerekētanga ngaru haere hiko-whatu, te whakarerekētanga hiko-whatu Kerr, te whakarerekētanga acousto-whatu, te whakarerekētanga magnetooptic, te whakarerekētanga pokanoa me te whakarerekētanga mārama ā-wāhi.
