Lisefa tsa "High frequency band pass" ke lisebelisoa tsa elektroniki tse etselitsoeng ho lumella feela mefuta e itseng ea matshwao a maqhubu a phahameng hore a fete ha a ntse a fokotsa maqhubu a kantle ho sebaka seo. Lisefe tsena hangata li sebelisoa lits'ebetsong tsa puisano, lisebelisoa tsa molumo, le lits'ebetso tse ling tsa elektroniki tse hlokang karabelo e nepahetseng khafetsa. Moqoqong ona, re tla hlahloba likarolo tsa bohlokoa tsa li-filters tsa frequency band pass, ho kenyeletsoa karabelo ea tsona khafetsa, bandwidth, le Q-factor.
Karabelo ea Khafetsa: Karabelo ea khafetsa ea sehlopha sa maqhubu a holimo se etsa qeto ea hore na e khutsisa mats'oao joang ka ntle ho "passband" le hore na e holisa matšoao a makae ka har'a passband. Sesefa se hlophisitsoeng hantle sa "high frequency band pass" se tla ba le phetoho e bohale lipakeng tsa "passband" le "stopband", e nang le ripple e nyane ka har'a passband. Sebopeho sa curve frequency response curve e khethoa ke moralo oa sefe, 'me e ka khetholloa ka maqhubu a eona a bohareng le bandwidth ea eona.
Bandwidth: Bandwidth ea "high frequency band pass" filthara ke mefuta e mengata ea maqhubu a lumelletsoeng ho feta ka har'a sefe ka ho theoleha ho fokolang. Ka tloaelo e hlalosoa e le phapang lipakeng tsa maqhubu a holimo le a tlase -3 dB, e leng maqhubu ao matla a tsoang ho sefahla a fokotsoang ka 50% ha a bapisoa le matla a mangata a passband. The bandwidth ea high frequency band pass filter ke parameter ea bohlokoa e khethollang khetho ea eona le kamoo e ka hanang matšoao a sa batleheng ka ntle ho passband.
Q-Factor: The Q-factor ea high frequency band pass filter ke tekanyo ea khetho ea eona kapa bohale ba karabelo ea maqhubu a sefe. E hlalosoa e le karo-karolelano ea maqhubu a bohareng ho bandwidth. Q-factor e phahameng e lumellana le bandwidth e fokolang le karabo e matla ea maqhubu, ha Q-factor e tlaase e lumellana le bandwidth e pharaletseng le karabo e fokolang ea maqhubu. Q-factor ea high frequency band pass filter ke parameter ea bohlokoa e khethollang ts'ebetso ea eona ho hana lipontšo tse sa batleheng ka ntle ho passband.
Tahlehelo ea ho Kena: Tahlehelo ea ho kenngoa ha filthara e phahameng ea frequency band ke palo ea phokotso ea lets'oao e etsahalang ha lets'oao le feta sefeneng. Hangata e hlahisoa ka li-decibels 'me ke tekanyo ea hore na sefe se fokotsa bokae ho passband. Sefefo se entsoeng hantle sa "high frequency band pass" se lokela ho ba le tahlehelo e nyane ea ho kenya phaseband ho qoba ho theola boleng ba lets'oao.
Impedans Matching: Tšitiso ea ho thibela ketso ke tšobotsi ea bohlokoa ea li-filters tse phahameng tsa maqhubu a maqhubu, haholo-holo mekhoeng ea puisano. Ho sitisa ho kenya le ho tsoa ha filthara ho lokela ho ts'oana le mohloli le ho thibela boima ho fokotsa lipontšo le ho ntlafatsa phetiso ea lets'oao. Filter e tsamaellanang hantle ea "high frequency band pass" e tla ba le tahlehelo e nyane le ho sotha.
Qetellong, li-filters tsa "high frequency band pass" ke likarolo tsa bohlokoa lipotolohong tsa elektroniki tse hlokang karabelo e nepahetseng ea khafetsa. Likarolo tsa bona tsa bohlokoa li kenyelletsa karabelo ea bona ea khafetsa, bandwidth, Q-factor, tahlehelo ea ho kenya, le ho bapisa ho hong. Setlhopha se hlophisitsoeng hantle sa "high frequency band pass" se lokela ho ba le karabelo e matla ea maqhubu, bandwidth e patisaneng, tahlehelo e nyane ea ho kenya, le ho bapisa ho ts'oana ho netefatsa ts'ebetso e nepahetseng.
