1) Gulu la cutoff frequency fp = wp / (2p) ndilofupikitsa malire apakati pakati pa gulu lodutsa ndi malo osinthira, ndipo kupindula kwa chizindikiro pa nthawiyo kumatsika mpaka kumunsi kwa malo opangira;
2) Band cutoff frequency fr = wr/ (2p) ndi pafupipafupi malire apakati pakati pa gulu ndi malo osinthira, ndipo kuwola kwa chizindikiro kumatsika mpaka kumunsi kwa munthu;
3) Kusintha kwafupipafupi fc = wc / (2p) ndi nthawi yafupipafupi ya mphamvu yamagetsi yochepetsera ku 1/2 (pafupifupi 3dB), nthawi zambiri, FC imagwiritsidwa ntchito nthawi zambiri ngati pass kapena band cutoff frequency;
4) Mafupipafupi achilengedwe f0 = w0 / (2p) ndikuti pamene dera lilibe kutayika, ma frequency a resonant a fyuluta, maulendo ovuta nthawi zambiri amakhala ndi maulendo angapo achilengedwe.
Kupindula kwa fyuluta mkati mwa gulu sikokhazikika.
1) pa sefa yotsika pang'ono kudzera mu gulu phindu KP nthawi zambiri imatanthawuza phindu pomwe w=0;Kupambana kwakukulu kumatanthauza kupindula pa w→∞;ndi malamulo ambiri amatanthauza phindu pa pafupipafupi pakati;
2) kwa gulu Resistance fyuluta, kukoka kukoka kwa lamba kuyenera kuperekedwa, ndipo kugwiritsa ntchito kuvunda kumatanthauzidwa ngati kusokoneza phindu;
3) Gulu lopeza kusintha voliyumu KP limatanthawuza kusiyanasiyana kwakukulu kwa phindu la mfundo iliyonse mu bandi, ndipo ngati KP ili mu db, imatanthawuza kuchuluka kwa kusiyana kwa phindu la DB.
Chitsimikizo chonyowa ndi ntchito yozindikiritsa kuchuluka kwa ma diagonal a fyuluta ngati chizindikiro cha w0, ndipo ndi index yoyimira kuwonongeka kwa mphamvu mu fyuluta.Kusiyanitsa kwa damping coefficient kumatchedwa quality factor, yomwe ndi index yofunikira yamakhalidwe osankhidwa pafupipafupi a * Valence band pass and band resistance Selter, q= w0/W.
W mu formula ndi 3dB bandwidth ya band-pass kapena band-resistance fyuluta, W0 ndiye ma frequency apakati, ndipo nthawi zambiri ma frequency apakati amakhala ofanana ndi ma frequency achilengedwe.
Kukhudzika kwa chizindikiro cha kachitidwe y kwa fyuluta ku kusintha kwa X kwa gawo lachigawo kumalembedwa ngati SXY, yotanthauzidwa ngati: sxy= (dy/y)/(dx/x).
Kutengeka si lingaliro ndi kukhudzidwa kwa chida choyezera kapena dongosolo la dera, ndipo zochepetsetsa zazing'ono, zimakhala zolimba kulekerera kolakwika kwa dera komanso kukhazikika kwapamwamba.
