Raina whakaroa whatuTe kī ki te ine i te wā kua whakatauhia
Hei whiwhi i tētahi tikanga tika mō te whakaputa i ngā whakaroa pono i roto i tētahi tirotiro matawai-wā, i ngā whakamātautau hihiri rānei, he maha ngā āhuatanga i terārangi whakaroaMe whai whakaaro ki te taumata hei whakaiti, hei whakakore rānei i ngā hapa e pā ana ki te taumata raina. I roto i ngā whakamātautau tirotiro me ngā whakamātautau hihiri kua whakatauhia e te wā, ko tētahi o ngā wāhanga tino nui ko te rārangi whakaroa whatu. Ko te rārangi whakaroa whatu noa he whakaata whakamuri, he whakaata takai rānei i runga i te atamira whakawhiti (Pikitia 1). I te wā e whiriwhiri ana i te atamira whakawhiti, me whai whakaaro ki ētahi tawhā i runga i te atamira me te taraiwa, te kaiwhakahaere rānei, nā te mea ka pā ki te tātari raraunga me te whakamaoritanga. Ko ngā tawhā whakahaere nekehanga matua e pā ana ki ngā inenga kua whakatauhia e te wā ko te whakaroa katoa, te nekehanga pikinga iti rawa (MIM), te auau, te tika, me te hapa miihini.
Ko te tawhā tuatahi me whai whakaaro ki te taumata rārangi ko te whakaroa katoa (T) – te wā e hiahiatia ana kia horapa te mārama ki te whakaata whakamuri.taputapu whatuā, ka hangaia te ara whakahoki. E pā tika ana tēnei ki te whānuitanga haere (L) o te wāhanga rārangi: T = 2*L/c, ko c te tere o te mārama i roto i te korehau. Ko te tawhā nui e whai ake nei ko te whakataunga whakaroa (Δτ), e pā ana ki te MIM o te taumata whakawhiti, ā, ka tatauhia mā te whakamahi i te tātai Δτ = 2*MIM/c.
He mea nui kia wehewehea te MIM me te taumira o te pūnaha nekehanga nā te mea e tohu ana rāua i ngā ariā e rua. Ko te MIM e pā ana ki te nekehanga iti rawa ka taea e te taputapu te tuku pūmau me te pono, nō reira e tohu ana i te āheinga o te pūnaha; i tētahi atu ringa, ko te taumira (te taumira whakaaturanga, te taumira encoder rānei) ko te uara iti rawa ka taea e te kaiwhakahaere te whakaatu, ko te uara iti rawa rānei o te encoder, e pā ana ki te āhuatanga hoahoa.
Ko tētahi atu tawhā wāhanga he rite te hiranga ki te MIM ko te āheinga whakahoki wāhanga, e pā ana ki te kaha o te pūnaha ki te tae ki te tūranga whakahau i muri i ngā nganatanga maha. I roto i ngā inenga wā-whakatau noa, ka matawai te wāhanga rārangi i roto i tētahi tawhiti (e rite ana ki tētahi whakaroa wā motuhake) ā, ka tuhi i ētahi tohu o te tauira ūnga hei mahi o te whakaroa wā. I runga i te kaha o te tohu o te tauira me te ōwehenga tohu-ki-haruru e tumanakohia ana, ko te uara toharite o ngā matawai maha he tikanga e whakamahia whānuitia ana i roto i ngā inenga wā-whakatau. Mā tēnei tukanga, he mea nui kia teitei te āheinga whakahoki o te wāhanga rārangi.
