Uhlalutyo lokulahlekelwa kunye nokulinganisa

Ukusetyenziswa kweendibano zekhebula kunye nee-amplifiers ezinengxolo ephantsi ukuze kuhlalutywe kwaye kulinganiswe ilahleko kunokunceda ekumiseleni amandla esignali, inqanaba lengxolo, kunye nokulahleka kothumelo lwenethiwekhi. Ukusetyenziswa kwezi zixhobo kwenza ukugcinwa kunye nokulungiswa kwenethiwekhi, uthumelo lwedatha kunye nezixhobo zonxibelelwano zichaneke ngakumbi kwaye zithembeke. Ibandakanya ikakhulu ezi zinto zilandelayo:

1. Linganisa ukulahleka kwesignali kwiintambo kunye nemigca kwaye uncede ekufumaneni apho ukulahleka kwesignali kukhoyo.

2. Linganisa umlinganiselo wesignali kwingxolo, oko kukuthi umlinganiselo wesignali kwingxolo.

3. Linganisa ubukhulu okanye amandla esignali, kuquka ukulahleka kwesignali kwiintambo kunye nemigca. Ezi zixhobo zibonelela ngemilinganiselo echanekileyo yokumisela amandla esignali yenethiwekhi kunye nesikhokelo sokulinganisa kunye nokulungiswa kwezixhobo zenethiwekhi.
