Subject: offset input "offset input" в контекстеThe extraction and amplification of the AC component of the ОАО output is performed by the second stage OA1. The DC tracking filter extracts the DC component of the signal and is used as an offset input to OA1. As OA1 would only amplify the difference it sees between the two terminals, only the AC portion of the incoming signal is amplified. The DC portion is effectively filtered out. заранее спасибо! |
