Hi all, this is my first post.
I find a lot of conflicting definitions of damping factor, damping coefficient, and damping ratio on the internet, and in some textbooks, when related to RLC circuits.
Sometimes I see the neper frequency described as the damping factor or damping coefficient. However, I sometimes see the ratio of the neper frequency to the resonant radian frequency described as the damping factor, damping coefficient, or damping ratio. This would be a contradiction, correct?
Sometimes when I see the damping factor, coefficient, or ratio represented by zeta, then it's the neper frequency over the corner frequency for a bode plot, but occasionally I will see zeta as the neper frequency over the resonant radian frequency. I don't think the two are one in the same, are they?
I realize some of this is due to loose useage of definitions and terms, but because some of it is outright contradictory, I need some clarification.
Can anyone point me to a site or source that adresses these discrepancies specifically, or at least has a definitive description of the terms in question? I've been to dozens of websites (and checked a couple textbooks) and there seems to be no agreement on the terms.
Thanks.
