N'edemede a, anyị ga-enyocha njirimara bụ isi nke ihe nzacha bandwit dị elu, gụnyere nzaghachi ugboro ole ha, bandwit, na Q-factor.
Nzaghachi ugboro ugboro: Nzaghachi ugboro ugboro nke elu ugboro band pass filter na-ekpebi ka ọ na-eme ka akara ngosi na frequency na mpụga passband na ole ọ na-eme ka akara dị n'ime paspọd. Ihe nzacha ngafe dị elu nke ahaziri nke ọma ga-enwe ngbanwe dị nkọ n'etiti paspọd na eriri nkwụsị, yana obere mgbịrịgba na paspọd. A na-ekpebi ọdịdị nke usoro nzaghachi ugboro ugboro site na nhazi nke nzacha, yana enwere ike iji ya mara ya site na ugboro etiti ya na bandwit ya.
Bandwit: bandwit nke ihe nzacha bandwit dị elu bụ ọnụọgụ nke frequencies nke a na-ahapụ ka ọ gafee nzacha na obere attenuation. A na-akọwakarị ya dị ka ọdịiche dị n'etiti mgbago elu na nke ala -3 dB, nke bụ ugboro ole a na-ebelata ike mmepụta nzacha site na 50% n'ihe gbasara ike kachasị na paspọd. The bandwit nke a elu ugboro band pass filter bụ ihe dị mkpa paramita na-ekpebi ya selectivity na otú ọma ọ pụrụ jụ na-achọghị akara n'èzí passband.
Q-Factor: Ihe na-akpata Q nke nzacha bandwit dị elu bụ ihe nleba anya nke nhọrọ ya ma ọ bụ ịdị nkọ nke nzaghachi ugboro ole nzacha. A kọwapụtara ya dị ka oke nke ugboro etiti na bandwit. Ihe dị elu Q dị elu kwekọrọ na bandwidth dị warara na nzaghachi ugboro ugboro, ebe Q-factor dị ala kwekọrọ na bandwidth sara mbara na nzaghachi nwayọọ nwayọọ karịa. Ihe na-akpata Q nke nzacha bandwit dị elu bụ ihe dị mkpa na-ekpebi ịrụ ọrụ ya n'ịjụ akara ngosi na-achọghị na mpụga paspọtụ.
