1. Whakarāpopototanga Hua
He pai te whakamahi i roto i te tuku-a-rua (ka taea te rahui) me te whakaorite tohu o te tuku pouaka-akomanga maha me te whatunga tohatoha e hiahiatia ana. Whakapaia ki a PHILIPS, NEC nga waahanga whakahuri hiko kawemai. Ko te ororongo i mua i te tiwerawera he iti-haruru ngaruiti ngongo whakakorikori pana-kumea ki te inihua rawa taonga. E 1 te whakaurunga me te 2 nga putanga, a he whakamarumaru o ia hononga ki runga i naianei. Ka taea te whakarereke i te peka whakaputa, te tohatoha ranei i muri mai. Ka whakamahia te whakairite-rua, no reira he ngawari, he watea hoki te whakatika i te papatahi o te tuku maha-akomanga. Ko te Attenuator me te kaiwhakariterite he mono-mai, na ka taea e nga kaihoko te kowhiri i te ahua kua whakaritea, ka taea ranei te whakarite. Ko te mana whakawhiti tino pono (he hiko raina ranei) me te hoahoa parewai me te aukati whatitiri ka whakarite kia mau tonu te mahi.
