In the case of an impedance mismatch, what are the comparative
advantages of a buffer over a passive attenuator? I assume that the
buffer will be much more expensive.
An impedance mismatch is usually a case of a high impedance driving a
low impedance. Adding passive

No, you are not attacking people around here. You are attacking common

Thanks all for the great explanations. Can anyone point to a good
layman's definition of impedance? I am math-oriented, but I am not an
