Re: Newbie view: have to be 'politically correct' to assylum insiders or beat up

Well folks, Steve's latest criticism of me is my use of the word "counter" as in:"... the correction voltage to COUNTER the EMF of the loudspeaker " A dictionary definition is:
" hinder or defeat by an opposing action " What I was referring to was that negative feedback will create an opposing or opposite voltage to effectively short out any extraneous voltages from the loudspeaker. Steve apparently thought that I was attempting to block any extraneous current flow from the loudspeaker. I believe that this is called current feedback.
Now current feedback is important in some applications. For example, DC servo-motors like to be current driven, and analog tape recorder record head drive circuits work well also with current drive. However, almost all power amps used in audio use negative voltage feedback to create a low impedance in order to 'damp' the back EMF from a loudspeaker.
