2.5: EFFECTS OF FEEDBACK ON INPUT AND OUTPUT …

WebAn amplifier is usually needed to raise the small transducer voltage to a useful level. A small voltage or current change at the input of the amplifier controls a much larger signal at the input of whatever circuit or instrument the amplifier’s output is connected to. Measuring and recording equipment typically requires input signals of 1 to 10 V. WebIt does not denote that the feedback will lead to changes that are good or bad.) Understanding the role of positive feedback has been crucial to scientists' research and eventual “discovery” of rapid climate change. ...
