1.1, daidaitawar ƙarfi
Daidaita ƙarfin haske shine ƙarfin haske a matsayin abin daidaitawa, amfani da abubuwan waje don auna DC ko canjin siginar haske a hankali zuwa canjin mitar siginar haske cikin sauri, don haka ana iya amfani da amplifier zaɓin mitar AC don ƙara girma, sannan a auna adadin da za a ci gaba da aunawa.
1.2, gyaran lokaci
