Affection of the Resistance of Signal Source for Return Difference of Negative Feedback Amplifiers
Liu Zu · Journal of Electrical & Electronic Engineering Education · 2004
It is a easily belied problem that the affinity of the negative feedback amplifiers and the resistance of signal source. In this paper, based on analysis of close loop gain of signal source, we discussed the important problem about affection of resistance of signal source to return difference of negative on the basis of control of output to input of the negative feedback amplifiers. It vouchsafed a physics view that affection of the resistance of signal source to return difference of negative.
