bmcculla said:Nigel I think you a bit confused. Gain for an inverting op amp: G = -Rf/Ri so you get G= -1/10 and G= -10/100 so you are going between -.1 and -10 gain not -10 an +10. Same problem with your non-inverting amp - you can't have an attenuator that gives negative gain.
eblc1388 said:Can gain ever be negative? How comes people suddenly find a new meaning for negative gain to mean a loss?
