1) Inta jeer ee band cutoff fp = wp/(2p) waa inta jeer ee barta xadka u dhexeeya band baaska iyo aagga kala-guurka, iyo faa'iidada calaamadda ee bartaas waxay hoos ugu dhacaysaa xadka hoose ee goob macmal ah;
2) Inta jeer ee band cutoff fr=wr/(2p) waa inta jeer ee barta soohdinta u dhaxaysa band iyo aagga kala-guurka, iyo suuska calaamadda barta waxay hoos ugu dhacdaa xadka hoose ee nin;
3) Inta jeer ee ku-meel-gaadhka fc=wc/(2p) waa inta jeer ee hoos u dhigista awoodda signalka ilaa 1/2 (qiyaastii 3dB), marar badan, FC waxaa badanaa loo isticmaalaa kaarka ama band-goynta inta jeer;
4) Inta jeer ee dabiiciga ah f0=w0/(2p) waa in marka wareeggu uusan lahayn wax khasaare ah, inta jeer ee resonant ee filtarka, wareegyada adag waxay inta badan leeyihiin soo noqnoqosho dabiici ah oo badan.
Faa'iidada shaandhada ku jirta guutadu maaha mid joogto ah.
1) shaandheynta hoose ee ka gudubka faa'iidada kooxda KP guud ahaan waxa ay tilmaamaysaa faa'iidada marka w=0;ka gudubka sare waxa loola jeedaa faa'iidada laga helayo w→∞;xeerarka guud waxaa loola jeedaa faa'iidada inta jeer ee xarunta;
2) shaandhada iska caabinta ee band, isticmaalka jiidida suunka waa in la siiyaa, iyo isticmaalka suuska waxaa lagu qeexaa sida ka soo horjeeda faa'iidada;
3) Kordhinta faa'iidada isbeddelka mugga KP waxay tixraacaysaa kala duwanaanshaha ugu sarreeya ee faa'iidada dhibic kasta ee band, iyo haddii KP ay ku jirto db, waxay tixraacaysaa qaddarka kala duwanaanshaha faa'iidada DB ee qiimaha.
Iskudarka qoyaanku waa shaqada lagu sifeeyo inta jeer ee shaandheynta sida calaamadda w0, waana tusaha mataleya qudhunka tamarta ee shaandhada.Ka soo horjeedka iskudarka qoyaanka waxaa lagu magacaabaa qodobka tayada, kaas oo ah tusaha muhiimka ah ee sifooyinka xulashada soo noqnoqda * Valence band pass iyo filter iska caabinta band, q= w0/W.
W ee qaacidadu waa xadiga 3dB ee band-pass ama filter filter band, W0 waa inta jeer ee xarunta, marar badanna inta jeer ee xaruntu waxay la mid tahay inta jeer ee dabiiciga ah.
Dareenka tusiyaha waxqabadka y ee shaandhada X kala duwanaanshaha halbeegga ka kooban waxa loo diiwaan geliyay SXY, oo lagu qeexay sida: sxy= (dy/y)/(dx/x).
Dareenku maaha fikrad la socota dareenka qalabka cabbiraadda ama nidaamka wareegga, iyo dareenka yar, way sii adkaanaysaa dulqaadka qaladka wareegga iyo sare u qaadida xasilloonida.
