Shaandhooyin caan ah waa shaandhooyin heersare ah, oo sidoo kale loo yaqaan filtarrada faragelinta, filimada indhaha ee loo isticmaalo kala qaybinta muuqaalka ama midabka.Marka loo eego qaabka loo qaybiyay spectrum, waxa loo qaybiyaa shaandhaynta band-pass, filter-off-off, filter filter, iyo filter gaar ah.Guud ahaan, waxa loo yaqaan shaandhada band-stop ama band-xakamaynta filter, taas oo loola jeedo filtar leh sifo muuqaal ah oo soo jiidasho leh iyada oo loo marayo iftiinka mawjada la bixiyay, inta suurtogalka ah, iyada oo loo marayo mawjadaha kale ee badan ee suurtogalka ah.Waa shaandheyn ilaa xad la jaray, kaas oo inta badan loo isticmaalo in lagu baabi'iyo ama lagu yareeyo iftiin gaar ah oo kor loogu qaado tamarta kale ee muuqaalka ah.Qoto dheer ee la gooyey iyo fidsanaanta aagga gudbinta ayaa ah cabbirrada cabbirka muhiimka ah ee tusmada.Shaandhooyinka shaandhada ayaa inta badan gudbin kara hirarka hirarka dhererka badankooda, laakiin waxay nusqaami karaan iftiinka kala duwan ee hirarka dhererka (bandka joogsiga) ilaa heer aad u hooseeya, kaas oo ka soo horjeeda habka isticmaalka iyo qalooca shaandhada bandpass.
