2. Nkwalite akara:Ebe ọ bụ na ike nke mgbama ngwa anya ga-eji nwayọọ nwayọọ daa mbà n'oge usoro nnyefe eriri anya, ike nke mgbaàmà anya nwere ike ịdị ike nke ukwuu mgbe ọ rutere n'ebe nnata anya.Igwe ọkụ na-ebu ụzọ dị na nnata ngwa anya nwere ike ịbawanye akara ọkụ eletrik ndị a na-adịghị ike ka ha wee nwee ike ịhazi ya nke ọma ma bufee ya.
3. Nzacha akara:N'oge usoro nnyefe eriri anya, enwere ike iwebata ụda dị iche iche na nnyonye anya, nke ga-emetụta ogo mgbaàmà.A na-ejikarị ihe nzacha nke preamplifier dị na onye na-anata anya na-enwe ihe nzacha iji wepụ ụda ndị a na nnyonye anya ma melite ogo mgbaàmà.
4. Nhazi akara:Igwe ihe nrịbama post-amplifier nwere ike hazie akara ngosi eletrik ọzọ, dị ka ngbanwe, demodulation, wdg, ka eweghachi ya na akara dijitalụ mbụ ma ọ bụ analog.Tụkwasị na nke ahụ, site na post-amplifier, a pụkwara imezigharị mgbaàmà eletriki ma mee ka ọ dịkwuo mma, dị ka ịhazigharị njupụta, ugboro na ihe ndị ọzọ nke mgbaàmà ahụ, ka o wee nwee ike izute ihe achọrọ nke usoro nkwurịta okwu na-esote.
5. Ngosipụta ọkụ eletrik:Enwere ike ịwepụta akara ọkụ eletrik arụpụtara na ngwaọrụ ndị ọzọ ma ọ bụ sistemu iji nweta nnyefe na ịkekọrịta ozi.Dịka ọmụmaatụ, n'ime usoro nkwurịta okwu fiber optic, enwere ike ibunye akara eletrik nke onye na-anata anya na-edozi na kọmputa, mgba ọkụ ma ọ bụ ngwa nkwurịta okwu ndị ọzọ.
