Te Mahi a te Reo Irirangi Analog
Ko te reo irirangi anaro tētahi o ngā momo whakawhitiwhiti kōrero tawhito rawa atu, ā, kei te whakamahia tonutia i ēnei rā. Ina tahuri tātou i te pūoro i tētahi reo irirangi anaro hei kimi i tā tātou teihana tino pai, kāore pea tātou e mōhio ki te uauatanga o tēnei hangarau māmā. I roto i tēnei tuhinga, ka tirohia e tātou te mahi a te reo irirangi anaro, mai i ngā kaupapa matua o ngā ngaru reo irirangi ki te tae atu o te oro ki ngā taringa o te kaiwhakarongo.
Ngā Kaupapa Taketake o te Ngaru Reo Irirangi
Ko ngā ngaru reo irirangi he momo ngaru hikohiko ka taea te haere i roto i te hau me te korehau. He maha ngā auau o ngā ngaru reo irirangi mai i te 30 Hz ki te 300 GHz. E rua ngā momo whakarerekētanga matua o te reo irirangi anaro: Te whakarerekētanga o te kaha (AM) me te whakarerekētanga o te auau (FM).
Te Whakarerekētanga Amplitude (AM): I roto i te AM, ka whakarerekētia te amplitude (te kaha, te rahi rānei o ngā ngaru) o te tohu reo irirangi hei whakaata i te reo, i ngā raraunga rānei e tukuna ana. Heoi, ka noho pūmau tonu te auau. He mea noa te whakamahi i te AM i roto i ngā purongo, ngā kōrerorero, me ngā pāhotanga puoro, ahakoa he iti iho te kounga o te oro i te FM.
Te Whakarerekētanga Auautanga (FM): I roto i te FM, ka rerekē te auau o te ngaru i runga i te oro, i ngā raraunga rānei e tukuna ana, engari ka noho pūmau te kaha. He pai ake te kounga oro o te FM i te AM, ā, e whakamahia ana mō ngā whakapaoho puoro.
Te Tukanga Tukatuka Tohu i te Reo Irirangi Analog
He maha ngā mahi matua o te tukatuka tohu i roto i te reo irirangi anarau. E whai ake nei ka whakamāramahia ēnei mahi.
1. Te Tuku Tohu mai i te Teihana Reo Irirangi
Ka tukuna ngā tohu e ngā teihana reo irirangi mai i tētahi pūihi tuku. Ka hurihia e tēnei pūihi te tohu oro hei ngaru hikohiko ka tukuna mā te rangi. Kātahi ka tae atu ēnei tohu ki te pūihi reo irirangi e whiwhi ana.
2. Te Whiwhinga Tohu mā te Pūihi
Ka hopukina e te pūihi o te kaiwhiwhi reo irirangi ngā ngaru hikohiko e tukuna ana e te teihana reo irirangi. Ka taea e ēnei pūihi te hanga waea māmā, te hanga tokotoko, te hanga hoahoa uaua ake rānei, i runga i ngā whakaritenga o te whiwhinga. Ka hurihia ngā ngaru hikohiko e whiwhihia ana hei tohu hiko ngoikore rawa e te pūihi.
3. Te Whakakaha Tohu mā te Whakakaha-mua
Kātahi ka whakanuia te tohu hiko ngoikore mā te whakamahi i te preamplifier. Ko te preamplifier, te preamp rānei, he wāhanga hiko e whakamahia ana hei whakanui i te tohu ngoikore mai i te pūihi ki tētahi taumata ka taea te tukatuka atu e te reo irirangi.
4. Te Tātari me te Kōwhiri Auautanga
I muri i te whakanuia, ka uru te tohu ki tētahi ara iahiko e mōhiotia ana ko te kaiwhakaara. Ka tīpakohia e tēnei kaiwhakaara te auau e hiahiatia ana i roto i ngā rau o ngā auau e whiwhihia ana e te pūihi. Ka taea e ngā kaiwhakamahi te tīpako i tēnei auau mā te huri i te pātene whakaara i te reo irirangi.
5. Te Whakakore i te Oro hei Tikina te Tohu Taketake
Kia oti te whiriwhiri i te tohu auau e hiahiatia ana e te reo irirangi, ko te taahiraa e whai ake nei ko te tango i ngā mōhiohio oro, raraunga rānei mai i te ngaru kawe. I roto i te AM, ka kiia tēnei tukanga ko te kimi i te kaha, i roto i te FM, ka kiia ko te kimi auau.
6. Te Whakakaha Whakamutunga
Kātahi ka tukatukahia te tohu kua tangohia te oro ki roto i te whakakaha whakamutunga hei whakakaha i te tohu i mua i te whāngaihia ki te pūorooro. Mā tēnei whakakaha whakamutunga ka whakarite kia kaha te tohu hei akiaki i te pūorooro me te whakaputa oro e rangona ana.
7. Putanga Tohu ki te Pūorooro
Hei whakamutunga, ka tukuna te tohu, ka whakanuia e te whakakaha whakamutunga, ki te kaikorero. Ka hurihia e te kaikorero tēnei tohu hiko hei ngaru oro ka taea e te taringa tangata te whakarongo.
Ngā Wāhanga Matua o te Reo Irirangi Analog
Haunga te mārama ki te tukanga, he mea nui anō hoki kia mōhio ki ētahi o ngā wāhanga matua e mahi ana i roto i te reo irirangi anaro, tae atu ki:
– Pūihi: Ka hopu i ngā ngaru reo irirangi e tukuna ana e ngā teihana pāho.
– Whakakaha oro: Ka whakapakari i ngā tohu ngoikore mai i te pūihi.
– Kaiwhakatikatika: Ka tīpako i tētahi auau motuhake mai i te tohu i whiwhihia.
– Kaitātari/Whakakore: Ka tātari i te tohu kawe taketake.
– Whakakaha: Ka whakapakari i te tohu ka tukuna ki te kaikorero.
– Pūorooro: Ka huri i ngā tohu hiko hei oro.
Ngā Painga me ngā Huakore o te Reo Irirangi Analog
Ahakoa kua roa te whakamahi i te reo irirangi anaro, kei a ia tonu ōna painga me ōna ngoikoretanga.
Te Hiranga:
– Ngāwari noa iho: He māmā noa iho te whakamahi i ngā reo irirangi anaro, ā, kāore e hiahiatia he pūkenga hangarau nui.
– Utu iti: Ko te hanga me te tango reo irirangi anaro he iti ake te utu i te hangarau matihiko.
– Whānui te Awhe: Ka taea e ngā ngaru AM te toro atu ki ngā wāhi tino whānui, tae atu ki ngā mano kiromita.
Ngā ngoikoretanga:
– Te Kounga Oro: He iti ake te kounga oro i te reo irirangi AM nā te mea ka ngawari te pokanoa.
– Te Whakararuraru: Ka pāngia e ngā momo whakararuraru pērā i te huarere kino, ngā taputapu hiko, me ngā whare nunui.
– Te Whai Hua o te Āhuarangi: Ko te reo irirangi anaro he iti ake te whai hua o te whakamahinga ā-whārangi i te reo irirangi matihiko.
Ngā Auahatanga Hou i roto i te Reo Irirangi Analog
Ahakoa kei te whanake tonu te reo irirangi matihiko, kei te ahu whakamua tonu te reo irirangi anaro me ngā auahatanga maha. He matatau ake, he whai hua ake hoki ngā pūihi me ngā kaiwhiwhi anaro, ā, he pai ake te kounga o te tohu. Hei tāpiri, ka whakakotahi ētahi reo irirangi hou i te hangarau anaro me te matihiko hei whakapai ake i te wheako whakarongo.
Whakamutunga
Ahakoa he hangarau tawhito te reo irirangi anaro, he huarahi whai hua tonu tēnei mō te hora i ngā mōhiohio me ngā whakangahau. Mā te tukanga e uru ana ki te tuku tohu hikohiko, te whakakore i ngā oro, me te whakanui i ngā tohu, ka hurihia e te reo irirangi anaro ngā ngaru hikohiko hei oro. Ahakoa ōna ngoikoretanga, pērā i te ngāwari ki te pokanoa me te iti o te kounga oro ki te whakataurite ki te reo irirangi matihiko, kei te whakamahia whānuitia tonutia te reo irirangi anaro, ā, e arohaina ana e te tini o te tangata huri noa i te ao.
I tēnei ao matihiko, mā te mārama ki te mahi a te reo irirangi anaro ka āwhina i a tātou ki te maioha ki ngā tukanga matatini kei muri i tēnei reo irirangi māmā. Mai i ngā ngaru reo irirangi e tukuna ana e ngā teihana reo irirangi ki te whakamarie o te whakarongo ki ngā purongo, ki tāu waiata tino pai rānei, he mea nui, he mea kore e taea te whakakore i te mahi a te hangarau reo irirangi anaro i roto i te hītori o te whakawhitiwhiti kōrero a te tangata.
