Kuzinhlelo zokusebenza ezingokoqobo, izibambisi ezilungisekayo zingalawulwa ngamafindo enziwa ngesandla, ama-potentiometer, amaswishi, nezinye izindlela, futhi zingalawulwa ukude ngokusebenzisa ukuxhumana kwedijithali noma ukuxhumana okungenantambo.Lokhu kuvumela abasebenzisi ukuthi balungise amandla esiginali ngesikhathi sangempela njengoba kudingeka ukuze kuhlangatshezwane nezidingo ezihlukile.
Kufanele kuqashelwe ukuthi izibambisi ezilungisekayo zingase zethule izinga elithile lokulahlekelwa kokufaka kanye nokulahlekelwa kokubonisa kuyilapho zinciphisa amandla esignali.Ngakho-ke, lapho kukhethwa futhi kusetshenziswa izibambisimandla ezilungisekayo, kuyadingeka ukuthi kucatshangwe ngokuphelele izici ezifana nobubanzi bokunciphisa, ukulahlekelwa kokufaka, ukulahlekelwa kokubonisa, ububanzi bemvamisa yokusebenza, nokulawula ukunemba.
Isifinyezo: I-attenuator elungisekayo iyisisetshenziswa se-elekthronikhi esibalulekile esisetshenziselwa ukulawula amandla esignali.Ishintsha izinga lamandla esignali ngokulungisa ukuncipha kwayo ukuze ihlangabezane nezidingo ezihlukene zohlelo lokusebenza.Ama-attenuators alungisekayo anethuba elibanzi lohlelo lokusebenza emikhakheni efana nokuxhumana okungenantambo, ukukala, nomsindo, futhi adlala indima ebalulekile ekusebenzeni nasekuzinzeni kwamasistimu kagesi.
