Site na ntinye nke voltaji dị elu, ụdị waveform ga-agbanwe agbanwe, àgwà nke mgbaàmà na-ebufe ga-ebelata, ọ ga-emetụtakwa onye na-ebufe ya. Akụrụngwa na nchekwa na-egwu egwu.

 

Netwọk mgbochi ahụ na-ewepụ nnyonye anya n'etiti sekit ugboro abụọ ma na-eme ka mmapụta mgbama pụta site na njikọ yiri nke sekit resonant.

 

Na nchịkọta, mmetụta nke igbochi netwọk bụ:

 

• site na mgbama ugboro a
• Gbochie mgbama ugboro ọzọ

 

Mgbe ị na-agafe mgbaàmà nke ugboro a, mgbochi ekwesịghị ịdị oke oke. Mgbe ị na-egbochi mgbaàmà nke ugboro ọzọ, ọ bụghị nanị na a ga-egosipụta nnukwu impedance na ugboro ọzọ, ma a ga-egosipụtakwa nnukwu nkwụsịtụ n'akụkụ elu na nke ala nke ugboro ọzọ, na-egbochi oge na-adịghị mkpa. ugboro ugboro.
