Ukuhlaziywa kokulahleka nokukalwa

Ukusetshenziswa kwemihlangano yamakhebula kanye nama-amplifiers aphansi omsindo wokuhlaziywa kokulahlekelwa nokulinganisa kungasiza ekuboneni amandla esinalli, umsindo, kanye nokulahleka ekuhanjisweni kwenethiwekhi. Ukusetshenziswa kwalawa madivaysi kwenza ukugcinwa kanye nokulungiswa kwenethiwekhi, ukudluliswa kwedatha kanye nemishini yokuxhumana enembile futhi ithembekile. Kubandakanya ikakhulukazi izici ezilandelayo:

1. Linganisa ukulahleka kwesiginali ezintanjeni kanye nemigqa futhi usize ekutholeni lapho ukulahleka kwesiginali kutholakala khona.

2. Kala isilinganiso sesiginali kumsindo, okungukuthi isilinganiselo se-sinal-to-umsindo.

3. Kala i-amplitude noma amandla wesiginali, kufaka phakathi ukulahleka kwesiginali ezintabeni nasemigqeni. Lawa madivaysi ahlinzeka ngezilinganiso ezinembile ukunquma amandla wesiginali yenethiwekhi kanye nokulinganisa ukuqondisa kanye nokulungiswa kwamadivayisi wenethiwekhi.
