Ukuhlaziywa kokulahlekelwa kanye nesilinganiso

Ukusetshenziswa kwamakhebula okuhlanganisa kanye nezikhulisi zomsindo ophansi zokuhlaziya nokulinganisa ukulahlekelwa kungasiza ukunquma amandla esignali, izinga lomsindo, nokulahlekelwa ekudluliselweni kwenethiwekhi. Ukusetshenziswa kwalawa madivaysi kwenza ukugcinwa nokulungiswa kwenethiwekhi, ukudluliswa kwedatha kanye nemishini yokuxhumana inembe kakhulu futhi ithembeke. Ihlanganisa ikakhulukazi izici ezilandelayo:

1. Kala ukulahleka kwesignali kumakhebuli nemigqa futhi usize ukuthola lapho ukulahleka kwesignali kutholakala khona.

2. Linganisa isilinganiso sesignali emsindweni, okungukuthi isilinganiso sesignali-kuya-nomsindo.

3. Linganisa i-amplitude noma amandla esignali, okuhlanganisa ukulahleka kwesignali kumakhebuli nemigqa. Lawa madivaysi ahlinzeka ngezilinganiso ezinembile zokunquma amandla esignali yenethiwekhi nokulinganisa komhlahlandlela nokulungiswa kwamadivayisi enethiwekhi.
