Ko te hanganga taketake o te tatau karati mamao

Ko te waahanga tuku ote tatau karati mamaoKo te tikanga ka wehewehea kia rua nga momo, ara, te kaiwhakahaere mamao(mamao kuaha karati)me te kōwae tuku. Ko te kaiwhakahaere mamao me te waahanga mana mamao mo te aratau whakamahi. Ka taea te whakamahi motuhake te kaiwhakahaere mamao hei miihini oti, a ko te raina puta waho he upoko puranga waea; Ka whakamahia te kōwae mana mamao hei wae i roto i te ara iahiko ka whakamahia kia rite ki tana whakamaarama titi. Ko te painga o te whakamahi i te kōwae mana mamao ko te mea ka taea te hono pai ki te ara iahiko tono, te iti o te rōrahi, te utu iti me te whakamahi pai i nga mea katoa. Heoi, me tino mohio te kaiwhakamahi ki te kaupapa ara iahiko. Ki te kore, he watea ki te whakamahi i te mana mamao.

Ko te tikanga, ko te wahanga whiwhi ote tatau karati mamaoka wehewehea ano kia rua nga momo, arasuper heterodyne karati tatau mamaome te aratau whiwhi whakaoranga supertatau karati mamao. Ko te ara iahiko demodulation super regenerative ka kiia hoki he super regenerative detection circuit. Ko te mea pono, he ara iahiko kitenga whakaora e mahi ana i roto i te ahua oscillation intermittent. He rite tonu te ara iahiko demodulation superheterodyne ki te reo irirangi superheterodyne. Kua rite ki te ara iahiko oscillation rohe ki te whakaputa tohu oscillation. I muri i te ranu ki te tohu auau kawe kawe, ka whiwhi te tohu takawaenga (te tikanga 465kHZ). Whai muri i te whakakaha me te rapunga auau takawaenga, ka whakahekehia te tohu raraunga. Na te mea kua whakaritea te auau kawe, he ngawari ake tana ara iahiko i to te reo irirangi. Ko te kaiwhiwhi superheterodyne nga painga o te pumau, te teitei o te aro me te pai te kaha ki te aukati i te pokanoa; He iti, he iti hoki te kaikawe regenerative super. He ngawari ki te whakaoti.
