Ukuhlaziywa kokulahlekelwa kanye nokulinganiswa

Ukusetshenziswa kwezinhlaka zekhebula kanye nama-amplifier omsindo ophansi ukuze kuhlaziywe futhi kulinganiswe ukulahlekelwa kungasiza ekunqumeni amandla esignali, izinga lomsindo, kanye nokulahlekelwa ekudlulisweni kwenethiwekhi. Ukusetshenziswa kwala madivayisi kwenza ukulungiswa nokulungiswa kwenethiwekhi, ukudluliselwa kwedatha kanye nemishini yokuxhumana kube okunembe kakhulu futhi okuthembekile. Kuhlanganisa ikakhulukazi izici ezilandelayo:

1. Kala ukulahleka kwesiginali ezintanjeni nasemigqeni bese usiza ekutholeni ukuthi ukulahleka kwesiginali kukuphi.

2. Linganisa isilinganiso sesiginali nomsindo, okungukuthi isilinganiso sesiginali nomsindo.

3. Linganisa ubukhulu noma amandla esignali, okuhlanganisa nokulahlekelwa isignali ezintanjeni nasezintanjeni. Lawa madivayisi ahlinzeka ngezilinganiso ezinembile zokunquma amandla esignali yenethiwekhi futhi aqondise ukulinganiswa nokulungiswa kwamadivayisi enethiwekhi.
