Ngā Taputapu e Hiahiatia ana hei Hanga i tētahi Reo Irirangi AM
Kua neke atu i te rautau te roa o te whakarongo a te reo irirangi ki ngā purongo, ki ngā waiata, me ngā momo kōrero maha atu. Ko te reo irirangi AM (Amplitude Modulation) tētahi o ngā hangarau tuatahi o tēnei mara. Ahakoa kua tere te whanaketanga o te reo irirangi FM me te hangarau pāpāho matihiko, kei te kitea tonu ngā mātāpono me ngā taputapu taketake e hiahiatia ana hei hanga i tētahi reo irirangi AM i roto i ngā akoranga hangarau hiko taketake. Ka matapakihia e tēnei tuhinga ngā taputapu e hiahiatia ana hei hanga i tētahi reo irirangi AM māmā me te mahi tahi a ēnei wāhanga ki te whiwhi tohu AM.
1. Pūihi
Ko te mahi a te pūihi he whiwhi i ngā ngaru reo irirangi AM e tukuna ana mai i te teihana reo irirangi. He maha ngā momo pūihi, engari mō tētahi kaupapa māmā, ka taea e koe te whakamahi i tētahi waea roa. Ko te roa o tēnei waea he 2 mita te roa kia whai hua ai ki te hopu i ngā tohu AM ngaru roa.
2. Koiri Whakatū (Inductor)
He mea nui te koiri whakahāngai, te inductor rānei, i roto i te tukanga whiriwhiri auau. Ko tēnei inductor he mea hanga i te waea pania kua takaihia ki roto i te koiri. Ka mahi tahi te inductor me te capacitor ki te whiriwhiri i ngā auau motuhake i roto i te teihana reo irirangi e hiahiatia ana mā te tukanga e mōhiotia ana ko te resonance.
3. Pūnga Pūnga Taurangi
Ko te pūnga iahiko taurangi, te pūnga iahiko taurangi rānei, he taputapu e āhei ai ngā panonitanga o te pūnga iahiko ki te whakarerekē i te auau oro o te ara iahiko LC (inductor-capacitor). Mā te whakarerekē i te pūnga iahiko o te pūnga iahiko, ka taea e koe te whakahāngai i te reo irirangi ki ngā auau rerekē hei rapu i ngā teihana reo irirangi.
4. Pūhiko Pūoko
He wāhanga matua te taiohiko kite i roto i te tukanga kimi, whakakore rānei i ngā tohu AM. Mā tēnei taiohiko ka taea te rere o te iahiko hiko i te kotahi te ahunga, ka taea ai te wehe i te tohu oro mai i te tohu kawe AM. I te nuinga o te wā, ka whakamahia ngā taiohiko germanium nā te mea he iti ake te ngaohiko whakamuri i ngā taiohiko silicon.
5. Whakautu
Ka whakamahia ngā ātete hei whakahaere i te rere o te iahiko i roto i ngā ara iahiko. He mea nui ēnei hei pupuri i te mahi tino pai o ngā wāhanga hiko rerekē i roto i te huihuinga reo irirangi AM. Me whakarite ngā uara ātete ki ngā hiahia motuhake o te ara iahiko e hangaia ana.
6. Ngā Taringa, Ngā Kaikōrero rānei
Hei whakarongo ki te tohu oro kua tangohia te oro, me whai pūrere whakaputa oro koe. Ko ngā taringaoro, ko ngā kaikorero rānei te tikanga mō tēnei kaupapa. I roto i ngā kaupapa māmā, he maha ngā wā ka whiriwhiria ngā taringaoro karaihe nā te mea he iti noa te hiko e hiahiatia ana, ā, he ngāwari hoki te tiki atu.
7. Papa Parāoa, Papa PCB rānei
He papa parāoa, he PCB rānei (Papa Arahiko Tā) hei tūāpapa mō te whakatakotoranga me te hononga o ngā wāhanga katoa. Mā ngā papa parāoa ka taea te whakarerekē ngāwari i te ara iahiko me te kore e hiahiatia he whakapiri, engari mā ngā PCB ka whakaratohia he otinga pumau ina oti te hoahoa whakamutunga.
8. Pūhiko, Pūtake Hiko rānei
Ko te wāhanga whakamutunga e hiahiatia ana he pūtake hiko. Ko te nuinga o ngā kaupapa reo irirangi māmā he iti noa te hiko e hiahiatia ana, nō reira he rawaka ngā pākahiko AA, AAA rānei. Heoi, ka taea te whakamahi i tētahi pūtake hiko o waho mō ngā ara iahiko uaua ake.
Te Mahi a te Porowhita Reo Irirangi AM Māmā
1. Te Hopu Tohu:
Ka hopukina e te pūihi ngā ngaru reo irirangi e tukuna ana e te teihana reo irirangi. He ranunga o ngā auau rerekē ēnei ngaru.
2. Kōwhiringa Auautanga:
Ka uru ngā ngaru reo irirangi e whiwhihia ana e te pūihi ki tētahi ara iahiko LC (te inductor me te variable capacitor). Mā te whakarerekē i te variable capacitor, ka taea e koe te whakarerekē i te auautanga oro o tēnei ara iahiko hei tātari i ngā auautanga e hiahiatia ana. Ko ngā tohu anake me ngā auautanga e ōrite ana ki te auautanga oro ka tukuna, ka whakanuia hoki.
3. Te Kimi:
I muri i te tātaritanga o te tohu e hiahiatia ana, ka tukuna ki tētahi taiohiko kite. Ka tangohia e tēnei taiohiko te tohu kawe mai i te tohu whakarerekē, ka taea ai te wehe i te tohu oro taketake (kei roto ko te reo, ko te puoro rānei).
4. Putanga:
Kātahi ka tukuna te tohu oro kua tangohia te oro ki te taringa, ki te pūoro rānei, ka hurihia te tohu hiko hei oro e rangona ana.
Kua rite koe ki te haere!
He nui ngā painga mātauranga o te hanga i tētahi reo irirangi AM māmā. Mā te mārama ki ēnei mātāpono taketake, ehara i te mea ka ako noa koe mō ngā hangarau taketake e ārahi ana i te whakawhitiwhiti kōrero reo irirangi, engari ka whakamōhio atu hoki koe ki ngā ariā whānui o te ahupūngao me te hangarau hiko. Anei ngā mahi whai hua hei tīmata i tō kaupapa DIY.
1. Huinga Pūihi:
Tīmata mā te hono i tētahi pūihi waea roa ki te papa taro, ki te PCB rānei.
2. Huihuinga Porowhita LC:
Honoa te inductor me te capacitor taurangi ki te papa taro. Me whakarite kei te hono te waea pūihi ki tetahi pito o te inductor.
3. Honoa te Pūhiko Pūoko:
Whakamaua te diode kite ki runga i te papa taro, honoa tetahi pito ki te ara iahiko LC, me tetahi atu pito ki te ātete.
4. Tāutahia te Ārai me te Taringa:
Honoa te ātete me ngā taringaoro ki te ara iahiko, me te hono i tetahi pito o te ātete ki te diode, me tetahi pito ki te taringaoro, ki te tāuru kaikorero rānei. Honoa hoki ngā taringaoro ki te whenua hei whakaoti i te ara iahiko.
5. Ngā Rauemi:
Me whakarite kei te tika te tūnga o ngā wāhanga katoa ki runga i te papa parāoa, i te PCB rānei, kātahi ka hono atu ki te pūtake hiko.
6. Tatūnga:
I a koe e mau ana i ngā taringa, ngana ki te hurihuri i te pūngao taurangi hei whakatika i te reo irirangi ki ngā auau rerekē kia kitea rā anō e koe he teihana reo irirangi ma.
Ka taea te whakarerekē me te whakawhānui ake i tēnei kaupapa mā te tāpiri i ngā mana whakahaere oro, he whakakaha oro, he whakamahi rānei i tētahi pūtake hiko kaha ake. Ko te mea nui kia taea e koe te whakarongo angitu ki ngā pāhotanga i runga i tō reo irirangi AM i hangaia i te kāinga—he wheako whakamīharo, he wheako ako hoki.
Mā te mārama ki te mahi a te reo irirangi AM me te whai wāhi o ia wāhanga ki tana mahi ka waiho hei tūāpapa pakari mō te hunga e hiahia ana ki te hikohiko me te whakawhitiwhiti kōrero. Kia ora, kia angitu hoki ā koutou kaupapa!
